How to show a constraint without having debug on?

I have a game that uses Matter physics. In this game, the sprite swings on a rope, which is a matter constraint. I need the constraint (or “rope”) to show when debug is off.

What is the best way to implement this? I’ve tried all sorts of ways from drawing a line, using the graphics object, turning debug boxes off for everything else, and others.

Could someone point me in the right direction?
