Steaming to a NEW group on Facebook and its not appearing in the 'Select Group' Dropdown?

[JenniferWMiller]

I've set up a NEW group on Facebook that id like to stream my zoom meetings into. I've set up the zoom app in the Facebook group.

last year (Stupidly)  I unticked a lot of groups, as my dropdown list was massive, now I cant find the settings option to 'reselect' groups to become available in the 'select group' dropdown for me to stream into?

Where is the settings section to select the Facebook groups to stream to? 

I know how to stream to a group but what do i do where the group isn't showing in the drop down menu?

Many Thanks
