Using student input with Geometry?

Is there a way to take a student input and use it in Desmos Geometry? I am about to enter a Pythagoras unit, and want students to enter an estimate for the hypotenuse, then have the Geometry app build a line segment of that exact length so they can see how their estimate measures up in the triangle.

Can you share a link? I’m not sure if it can be done within the geometry area, but could be done within the graph space.
