Array revolve in geometry node

Hello, I’m trying to make a video and would like to change the number of iterations of around the z axis parametrically to go smoothly from 4 to 5 to 6 to 7… corners, without having to remodel or tweak around the vertices until they fit together. I am not very familiar with geomerty node, so I’m not sure if this is possible, or how to do it. Does anyone have an idea how to achieve this ? For the moment, I only use a mirror and an array modifier
