Draw freehand in Gdevelop

Hello, I would like to know if it is possible to make a game in which I can draw figures by hand with my finger, I was seeing the Shape Painter method, to draw, but as you know, it is not exactly what I am looking for. I would also like to know if it is possible to call an action when said figure is formed, say that there are three points that form the triangle, and I must draw for each of them to form the figure, if I do, that such a thing happens. And of course, how do I do it? I know it’s a lot, but before I go further, I would like if it is possible to do this in this engine, and if not, in which other if you know?

I translated this using Google translator, sorry for any typo.
