How do I fix my Chucky’s doll arm?

So I had this MezcoToyz Chucky doll for a while and the arm got ripped off which wouldn’t be a problem since you could always attach it back but this time the price to attach it broke and now I can’t attach it, I could glue it back but I really want the arm to move could anyone please help me?

Photo one is the broken piece and the second one is what it looks like when ripped off safely
