Is there a PHP public library to limit group for an app?

Hi everyone :slight_smile:

I would like to check the “limit to groups” checkbox and add these groups to limit my app when I install it and is enabled :point_down:

I found the enableAppForGroups() from IAppManager.php :point_right: server/IAppManager.php at 18431c2fe920c1f72f68f3c33a7c2a40ccb70c0a · nextcloud/server · GitHub

I have added this function in my Register :

But, it doesn’t work :confused:
Maybe it’s not the right library I should use ? :thinking:
