Allow clear cache options for BE_USERS TYPO3?

You need to add this typoscript to their user accounts:

options.clearCache.pages = 1
options.clearCache.system = 1

Source: https://docs.typo3.org/typo3cms/TSconfigReference/singlehtml/#clearcache-pages

You can set this via UserTSConf for each user or user group:

options.clearCache.all = 1
options.clearCache.system = 1
