How do you animate a tool

So I’m trying to make a fnf character in a tool that moves when you click keys except whenever I try to animate it I start having problems.
When I use animation editor it wont let me rotate or move the parts of the tool, and when I use moon animator it doesn’t let me insert the model

I’ve seen similar things to what I’m trying to do before and i cant figure out how it was done

This might be what you’re looking for.
