Can't figure out how to make First person animations work.

So I made a first person character. I used the mannequin from the Animation Starter Pack to make a character shadow for immersion. I got the animations for the mannequin to work but for the life of me I can’t figure out how to get the arms for the weapon to work. There are 2 weapons decedent from a base gun class, Rifle and SMG (from first person weapon bundle). Basically I attached the weapons to the first person mannequin arms from the first person template. Then on begin play the Rifle spawns on a scene component that’s attached to the camera. I can switch to the SMG by pressing 2 then back to Rifle by pressing 1. I’m not sure If I need a separate animation blueprint or if there’s somehow a way to do it in the same one as the character shadow.

I’m trying to use the animations for the Mannequin arms for the weapons. If anyone can tell me how I can get the animations working I would like that a lot.
