Triggering morph targets in sequencer

Hi. I’m trying to find a tutorial/explanation of how to trigger morph targets in sequencer, oriented to animations like blinking or changing facial expressions… I can find very little and what I find it’s quite confusing… I guess I could create in sequencer an event funtion linked to the morph… but it seems I’m missing something as it doesn’t work… I think this should be an easy way but…
