For somereason this feature is not working for me, the drop down is always empty. can someone help?
Looks like bitwarden made major changes in access control lately, which broke some functions.

The function is not broken. It just doesnt work intuitively.
If you execute these actions via the admin (organization) console it will work just fine.
