[1.19.4, SOLVED] Complex custom player animations

[LeeCrafts]

I would like to create player animations upon holding and attacking with an item. Specifically, I want the player to move its body and both arms while using the weapon (in the third-person view). Currently, I am playing around with IClientItemExtensions (https://forge.gemwire.uk/wiki/Custom_Item_Animations), but I do not see a way to move the player's body using this method. Would I have to use an animation engine like Geckolib? 

Edit: My solution was to use an external animation library, as suggested by @Ninjaguy169. I used KosmX's PlayerAnimator (https://github.com/KosmX/minecraftPlayerAnimator), and it was helpful to look through the library's Discord server and GitHub.

I suggest using an external animation library (PlayerAnimator, for example).
