Forward an assigned number

I am trying to forward an assigned User number in Microsoft Teams.  When I login to the desktop version of Teams, I go to the profile picture, then settings, then calls.  I chose Forward , but I can only forward to voicemail.  Other article I have read, allows me to forward to other options via a drop down choice box.  My account does not seem to have the drop down - see screen shot.

Any help would be appreciated.
