Add Transparent Window to Existing

All I want to do is to add a third window between them, and I can't make it work. I've read that I need to create a new layer and 'Add Alpha Channel' but that option is greyed out. I also read that if I do Windows --> Dockable Dialogs --> Channels and see 'Alpha' as an option (which is there) that means the Alpha Channel has already been added, which I guess makes sense because there are already two 'windows' on the image that are transparent.

With that information, could someone please walk me through the steps to create a third window that will be transparent? The online videos and help I've found show me how to remove the background around a part of an image to make it transparent, but that's not what I need in this case.

Thank you very much for your help!

Without an image as an example I am left with assumptions.
What I could suggest with the idea I have in mind about the situation is that you could use ready-made images like those found for example at: https://www.freepik.com/free-photos-vect...ransparent
Another option would be to use the Clone Tool and copy one of the windows to create the third.
