user management

Hello,

is there a possibility to give an user access to "Datacenter" --> "Backup" so that the user is able to manage his scheduled backups?
I created a group and an user who belongs to that group. After that i created a pool and added the VMs and storage to it. Under created 3 permisions:
/pool/"POOLNAME" --> "GROUP" --> "PVEAdmin"
/pool/"POOLNAME" --> "GROUP" --> "PVEVMAdmin"
/pool/"POOLNAME" --> "GROUP" --> "PVEDatastoreAdmin"

Do I have something missed?

And a second questioned: is there a possibility to hide the "subscription" tab for users?


Thanks in advance for any help.

Best regards from Austria,
Patrick
