About nerdy's geckolib triggering 1st person animations

Hey so i've been searching for a solution for the problem i have right now with my mod, let's me explain:

So first of all i'm making a Sniper that has custom animation in first person, the problem is that if i'm playing with more friends and they have the same item as me in the inventory and i trigger the animation, the animation will play for them as well (only i can see them doing the animation, they can't see it), so basically that's the problem.. whenever i trigger the animation for me the animation will play for their characters too.
