Trying to make a emote but i can move the arms and head as well

so i made a “on knees” animtion and put it in the action layer to act as a emote, how can i make it where i can use my arms and head but the legs and camera stay as they should be in the animation?
and i used it in the action layer because i tried it in the fx as a lay animation and i can do that because i would need to go down and i dont have play space so i can only use sitting play and standing play. please help if you have any ideas, thanks <3

You can use the base layer for that.

My prefab controller do something similar of what you describe.
