ModifyButtonBarEvent

New in version 12.0: This event serves as a direct replacement for the removed hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['Backend\Template\Components\ButtonBar']['getButtonsHook'].

The PSR-14 event \TYPO3\CMS\Backend\Template\Components\ModifyButtonBarEvent can be used to modify the button bar in the TYPO3 backend module docheader.
