How to export shapekey animation to unity

I’m trying to export a model using shape keys, and i’ve tried alot but everytime there is just one action that does nothing.
I’ve followed this tutorial right here> But no results.
Also when he presses I, he gets a notification which i do not get. I can just choose between multiple ways to insert a keyframe. I figured i had to press the LocRotScale.

I hope anyone can help me with this frustrating problem.

This is the tutorial I used to do it. Hope it helps
If you still need some more help. Let me know :slight_smile:
