How to put a 2d animation in a dialogue and how to create a charm bar like in dragon age?

so i am creating a simple 2D dating sim (similar to mass effect/dragon age dialogue system including the camera setting) in a 2d platform side scroller and while building the dialogue using the plugin of: Dialogue System

I notice that I didn’t know how to upload a 2d animation for the npc or main character when the dialogue plays I try going to google it but there is only 3d animation tutorials which is not what I need for the game project also the charm bar (that accumulates scores depending on the dialogue choices) is not working

i am incredibly rusty can someone help me?

p.s. i am a slow learner but i am willing to learn
