Control Rig - Get Morph Target and Animate them

Hello there,
I have a character that comes with blendshapes (morph Target) and I’d like to be able to animate them in sequencer.
I’ve read somewhere that there is a way to do this with control rig, adding a controller and then linking all the morph target on it so you can them key them in sequencer, but I couldn’t find a way to properly do that.
Does anyone know how to do this ?
Thank you !
