Didnt mean to add the bug tag

As far as I am aware, this is impossible. You can't altar player animations or actions with a datapack. However, you may get a different answer from people who are more familiar with animations in general- try posting here: https://www.reddit.com/r/MinecraftCommands/

In the future, please do not create an issue asking for help- these are not a discussion board. Use any other services I use like discord (preferred), reddit, planet minecraft, curseforge, etc.
