Circular Pursuit Curve Problem

Im trying to figure out if theres a way on how to create a pursuit curve in desmos In order to graph the interaction in some gameplay footage of mine,

The person being chased is running around in a circle where the center is ( 0,0 )

And the chaser starts outside of the circle and for this example they are both the same speed and the radius can just be 5 units

The only resources I could find are for the person being chased in a straight line but I need them running in circles.
