How do I creat a first person character animation? 4-26

I just need the right arm to lift up and in front of the camera as if he is looking at his watch. I’ve looked everywhere i just cant figure out how to make my own animation.

I was following this tutorial Creating 3D UI: Tutorial in UE4 - YouTube and all he says is " i made these 2 animations without further elaborating how to. (at around 7:40)

I’m using the first person character so its only the 2 hands

Can anyone help me out?

Thank you! Version 4.26.2 4-26
