Hello, I'm trying to use this action in one of the repos that I contribute to, but it seems you can only request review from collaborators, see this test action. Since our repo has many contributors, giving collaborator rights to each of them who is willing or wish to review is not really feasible.
I'm thinking perhaps this action can be extended to write a comment to mention the people that cannot be requested for review because they don't have collaborator rights. I searched for other actions and the closest thing I was able to find that has something similar to what I want to do is this action, which seems to be not longer maintained and only supports mentioning according to labels, so I think this action is closest to what I want.
