Configuration 

This extension ships its frontend TypoScript and its backend page TSconfig in two forms: as TYPO3 site sets, and as classic static templates plus page TSconfig files that are selected on a page. Both forms read the very same files, so they configure an installation identically.

Pick one of them per site and stay with it — see Do not combine both for what happens otherwise.

What the sets contain 

The extension ships one content element, so it ships one component set and one aggregate set that depends on it.

Set Delivers
fgtclb/academic-persons-edit-profile-editing The Profile editing content element: its TypoScript (plugin.tx_academicpersonsedit) and the page TSconfig that makes the content element selectable in the backend.
fgtclb/academic-persons-edit Everything above. This is the set to use unless you deliberately want a subset.

Both depend on fgtclb/academic-base-ctype-group, the set of EXT:academic_base that labels the content element group all academic extensions sort their elements into.

The plugin renders partials of EXT:academic_persons, but it reads them from Resources/, not from that extension's TypoScript. There is therefore no set dependency on any fgtclb/academic-persons-… set, and none is needed.

The content element is hidden by default 

EXT:academic_persons_edit hides its content element for the whole installation and brings it back per component. Whichever of the two mechanisms below you use, it is what makes Profile editing selectable in the backend again — without one of them the content element is not offered, and existing records keep rendering.

On TYPO3 v12 only the page TSconfig file is a candidate: the site set is not read there. On that version the same file also carries the entry of the new content element wizard, which v12 builds from page TSconfig rather than from TCA (the TCA based wizard arrived in v13.0, Feature: #102834).

Include the site set 

On TYPO3 v13, add the set to the config.yaml of the site that should offer the content element:

config/sites/my-site/config.yaml (diff)
 base: 'https://example.com/'
 rootPageId: 1
+dependencies:
+  - fgtclb/academic-persons-edit
Copied!

Include static templates 

For an installation that still configures its frontend through sys_template records — which on TYPO3 v12 is every installation — the same files are registered as static templates and as selectable page TSconfig files.

Include static TypoScript 

Edit the sys_template record of the site root and add the entry to Include static (from extensions):

Entry Delivers
Academic Persons Edit: Profile editing (academic_persons_edit) The TypoScript of the Profile editing content element.
Academic Persons Edit: All components (academic_persons_edit) Every component this extension ships, in one entry.
Academic Persons Edit: Path up to 2.3 (deprecated, use All components) (academic_persons_edit) The same as All components, for a record that still stores the path of version 2.3. Deprecated, removed in version 4.0, see Deprecation: The static template path of version 2.3.

Include static page TSconfig 

Edit the page record of the site root, tab Resources, field Page TSconfig, and add the entry:

Entry Delivers
Academic Persons Edit: Profile editing (academic_persons_edit) Makes the Profile editing content element selectable, and configures its entry in the new content element wizard.
Academic Persons Edit: All components (academic_persons_edit) Every component this extension ships, in one entry.

The setting is inherited by every page below the one it is set on.

Do not combine both 

This can only happen on TYPO3 v13. A site that uses the site set and the static template reads the shipped files twice. The site set is applied before the sys_template record, so the second read happens after the site settings and after config/sites/<site>/constants.typoscript — and it resets every constant the extension ships a default for back to that default.

Nothing else is damaged: the Constants and Setup fields of the sys_template record, the page TSconfig of a page and the page TSconfig files selected on a page are all applied afterwards and still win. Use one mechanism per site and the question does not arise.
