How to bind multiple actions to a character rig?

Question

Adobe After Effects

Hello, I do not know how to formulate the question correctly. The bottom line is this - in After Effects, using the duik script, a character rig was made. I made the walking animation. But according to my scenario, it should be that - the character approached the object and, say, raised his hands, or began to interact with it. Well duck, how do I make this interaction with the object? Or do I need to do it all in one composition, right after walking?
I think that you need to use all sorts of markers? And then change them so that the animation changes?
Please throw a tutorial on this topic, or what to google.
thanks in advance
