Hey @anon43131755,
if i got you right you’d need READ and CHANGE.
This permits the role to - well - read a ticket (if you search for it) and edit an existing ticket.
That way you can’t create a ticket for said group, nor see those tickets in an overview or act as an agent for that group.
To break all rights down for you:
READ - Have a look at existing tickets.
CREATE - Create tickets.
CHANGE - Edit existing tickets.
OVERVIEW - See tickets in an overview.
FULL - Full access. Makes you selectable as owner for any ticket of that group.
cheers
