Add procedural attack animation, geckolib plugin.

Hello, what happens to me is that I am making an entity that has been assigned animations with the geckolib plugin but I want its attack to be from a distance, what happens is that the automatic animation that the plugin makes is of a physical attack (or at least that's what I could see) so I deduced that I should call the procedural animation while attacking, I looked for tutorials on the internet but they are all outdated compared to the version I use, which is the last one released by its creator.
I tried for a long time but I still can't, I'm kind of slow with these things xd.
Could you tell me how to solve this? thank you!
