How to combine separate body and face animations metahuman?

Anyone found any good working solutions? The video above is from my understanding basically a rig that has the face already included, not like with Metahuman where they are almost like 2 separate entities…

Updating my reply with the link to the topic I’ve created with a working (so far for me) solution: Metahuman: combining facial and body animation in sequencer without losing head rotation data
