Random Waypoint Generator for each level.

Hello all this is my first message here, i hope you all fine and well.

I am creating an Vr space game 3D project that my ship follows certain waypoints(start to finish).

I created waypoints manually by using empty gameobject and i wrote script that my player follows the waypoints.

But the thing i want is to create random waypoints(1-5) for each level.And my player to follow.

I created some zones with colliders but couldnt able to find a way to generate random Waypoints in these zones.
