Use mouse draw line in the 2D,how to do?

okay that makes sense, thanks so much for answering! And one more quick question that you might know how to approach, i want to use the drawing in a notebook/journal widget that the player can open and it has multiple pages. Would there be a way to only have the drawings show when youre on a certain page in the notebook. I was trying to mess with the visibility but i’m not sure where to do it
