How to make a GUI for animations/emotes? None of the videos help or work for me

Hello! I started developing a game yersterday, it's a very simple hangout spot for me and my friends. I want to add animations/Emotes GUI for my game but every article or roblox video does not help. I want the animations to function outside of studio too.

I'm very new at this since this is the first time i'm even trying to script (and honestly i just watch videos and copy the script) so sorry if I get annoying with not understanding. I made the GUI itself I just need for the animation to play when I press it and for it to stop after you press it again.
