How to edit a poly~ subpatch while in use?

I recently was using this tutorial https://cycling74.com/tutorials/polyphonic-synthesizer-video-tutorial in order to figure out how to use poly~, and everything has been working fine except for one issue. Since I am on Windows, I cannot "option-click" the window title bar to bring up any option to edit the abstraction/in-use poly~ patch as shown in the tutorial. When I take the poly~ object out of read-only mode via clicking the bottom left option, I cannot update it to be in immediate use. Adding objects like [in 2] or [out~ 3], for example, does nothing to the poly~ object.

Further, from looking up my problem, some pages said to Alt+Click the window title bar. This also did nothing.

How do I update an in-use poly~ object such that all changes apply?
