Get skeleton mesh component in child actor

I’m currently working with UE5 to animate the 3D model with chat bot.

Here is my current BP. I would like to access skeleton mesh component inside my child actor. And play the animation on this skeleton.

In this child actor it also have its own anim instance animation but it just want to override with another animation temporary. When I click on play and type in the trigger, the default anim stopped but my new animation didn’t play.
