Donut Wheel | Click to expand for Details

I am trying to make a donut wheel that when a user clicks on one of the section it expands and shows a text field describing what that specific position in grater details. The donut wheel specifically shows like the keyword of the process (this is a process donut wheel) such as “Company Registration” and when the client clicks on the “Company Registration” part of the wheel that section will expand and show in further details (max. 150 characters) what this process includes.

I am no coder but I hope there is someone in the community who might be able to help me with this.

Currently I do have a few concepts that I have looked from other people. By far this is what I got on CodePen (Click here). I am not aware on how to get the expand feature, on click.
