How to blend 2 animations into the same character and make that character do the blend animation in movie sequencer in Unreal Engine 5?

So I have 2 animations from the same character. One is him walking and the the other is just him talking and moving his head only. I want to combine the both walk animation and talk animation together so he could talk while walking. I ALSO want to put him in a movie sequencer and do that blended animation in a specific time. I’m a bit new to UE5, especially on making blueprints, so I was wondering if someone can help explain to me how to do it?

make a level seq
drop the character in
add animation tracks under the character
with one anim on top and one below sde them so their edges overlap

otherwise use an “anim montage”
