How to assign groups as the owners of Autodesk Media Storage


for the case, the Media framestore remains full after deleting projects, Autodesk suggest (among other things) to:

->To avoid this behaviour ensure that the media storage volume directory used for Flame, has both the
->Operating System admin user and admin group assigned as the owners:

->For macOS:
->User = ‘main macOS Admin user’
->Group = ‘wheel’

The command ‘groups’ does not list the group ‘weel’, but staff, everyone and many more…

What do you suggest in order to add those two groups as the owners?

Thank’s a lot!
