It doesn't seem to be supported to have triggers on the GroupMembership object.
I want to update a field on the user object every time a user becomes part of certain public groups.
Neither workflows or triggers are possible on the group membership object.
Does anyone have ideas on what could be an alternative solution?
What I'm thinking off too is having a scheduled apex job that runs for example twice a day but I'm not too much in favor of that.
Any thoughts?
