Person Change Rule when End-dating Benefit Group

Summary:

Has anyone successfully setup a Person Change/Data Change rule to attach to and trigger a life event when a Benefit Group assigned to a person is end-dated?

I've successfully created one when initially assigning a specific benefit group to someone; however, cannot seem to figure out to trigger when a specific benefit group is end-dated. Thank you!!!

This is the configuration I used when assigning a Benefit Group that is working correctly. Need help creating one to trigger when end-dating.
