Tummy time

Anyone have tummy time advice? My 4 1/2 month old HATES tummy time. He’ll be on his tummy with toys and I’ll be on the floor with him where he can see and he makes it like 10 mins. I’ve tried turning baby bum on on my phone so he has that but it didn’t work either. Also I seen that I can put a mirror in front of him. But I don’t know what to do to get him to do tummy time. He rolls over if he’s on the couch (I’m there making sure he doesn’t fall) he holds his head up really good and pushes up with his arms but he WILL NOT do tummy time longer than like 10 mins. He doesn’t like being in his tummy. He gets mad.
