Interact with procedural mesh hosted on a GameObject created at runtime

I have a script that creates a GameObject each time the player clicks and drags in 3D space. Then a procedural mesh is created using the player's mouse inputs. The procedural mesh is hosted on the created GameObject.

The process repeats itself, the player clicks and drags again, a new GameObject is created, and a new procedural mesh is drawn, hosted on that GameObject.

I'd now like the player to interact with each of the procedural meshes / GameObjects

Is this possible? I decided to create a new GameObject for each procedural mesh because I plan to add data to each GameObject, and when the player clicks on the mesh, the data can be displayed.

How do I apply behavior to a GameObject that was created at runtime?
