Make two animations BP work together

Hi,
A newbie here!
I am using a MH with lip-sync and trying to use another bp to make it look at the camera. Maybe I am overshooting, but coudn’t find info on doing it otherwise.
The thing is, the face in MH has the speechAndLook_Anim that blends Face_AnimBP_Lookat:


And the problem comes when I uncheck Disable Post Process Blueprint:

If checked, the MH looks at camera, but does not lip_sync. When unchecked, it lip_syncs but does not look at camera. How could I make it work??

Thanks for reading!

Quick update:
I have bought a lookat plugin, but to now avail. It works on its own, but then the lip sync animations do not play…
