Fps Multiplayer animations not working.

Hello everyone I'm on unity 2021.3 and I am creating a fps multiplayer game.I want that the local player can just see his arms and his gun but that he can see the entire body of all the others players with their animations.

I already created the scripts for disable local/external things but it doesn't work for the animations behaviours.
When I walk, the others players also walk but if i put the animation script or the animator in disable !isLocal behaviours, others players are stuck with the idle animation.

Please Help Me.

(Sorry if I have a bad english my first language is french.)
