Animate Thirdperson Mixamo when start play or trigger box

Hi

I have a Character from Mixamo with 12 motions and I want this actor to be placed in my level but not playable. How can i make this actor just to start animate all the different motions in place and in the meantime I will run around and with my thirdpersonCharacter to inspect it in game mode.

I managed to create thirdperson Character but have no knowledge with animation in general.

regards steel
