Unfortunately it's a bit tedious and requires some Timeline knowledge since the expressions are part of the animations. You'd need to essentially remove all the nodes for expression morphs in Timeline, set all their values to zero, and then save the pose. Rinse and repeat for each animation.
Used it as a makeshift body-writing tool, obviously not intended and the result was pretty meh, but very fast and easy, well-made plugin that can be used in different ways
True, earlier while prototyping the text on body, it was supposed to follow along the geometry of the body, but it resulted in warping that didnt look that good. So for now, I settled for what is essentially a kind of wall of text inside the body.
I will be looking into this in the future because it is pretty distracting, especially in VR that there is essentially just a text dimension inside the body, you do give me an idea for a separate plugin though.
