Playing an animation only visible to your client

How would I be able to play an animation (specifically for your own character) that is visible only on your client?

I’ve tried finding a topic similar but I couldn’t find a single one

Roblox’s animations were made with that purpose, that the animations were automatically replicated when play in Client.

One way to do this but only for the client (without replication) manually moves C0 and C1 of the Motor6D of character.

Is there a way to play a keyframe animation without replication and without using motor6d?
