Re-assign MR to a different user after X days with no feedback from assigned user
On the MRs for which I receive the "It seems that there hasn't been any activity concerning this merge request for some time." it seems that a different/complementary (previous?) approach would be to change the assignee.
Something like, hey @login you haven't found the time to review this, let me try someone else, you're still welcome to review this in case you end up having some availability
