I need to create a Sharing Rule that only allows Users to see Campaign Members where they are the record owner of the Contact or Lead that corresponds with the Campaign Member.
Sharing Rules don't support the formula criteria I would be using, and I'm not finding a 'CampaignMemberShare' object that I can reference in apex.
Is there another way I might be able to attack this? Am I missing something? Or am I out of luck on this requirement?
