Basic animation question

I’ve been trying to find an answer to this in the tutorials.
How do I change an animation in the animation blueprints?
I’m using the basic 3rd person blueprint.
I don’t want to use the idle animation given in the animation blueprint.
I have another idle animation I found in another pack.
I’ve already added the pack to the project.
I can’t see how you can add it to the list of animation loops for the character.
Do I need to export that animation then import it?

You have to find it in its locomotion graph and replace the clip in its state node there. Thats actually a really trivial thing tbh and if you dont know how that, I highly encourage you to watch this training series first before going any further:

Its extremely useful and will teach you all the required basics to get a simple custom character up and running in the engine.
