Assign ticket to a user in that group

I've found a thread in GLPI with a answer from a dev to make a request for this feature (link to the thread): https://forum.glpi-project.org/viewtopic.php?id=157161

My idea is to filter the tech who was in that group, example:

Open a ticket, assign to GROUP A, only the Tech in GROUP A will be possible to assign to that ticket, not all tech in that entity.

If this feature was already implement, i dont know how to activate and dont see any plugins or tutorial to do that.
