When will role insights suggest an update to a role?

I created a role that included three identities in it. I then requested one AD group for the three identities in that role. My goal was to test out the process whereby Role Insights sees that these three identities have gained some additional access and then the suggestion that the access should be added to the role.

I’m not sure what I’m supposed to do to make Role Insights do what I’m hoping it would automatically do. And then, if it indeed does find that the new access should be added to the existing role, where will that suggestion show up at?
