Version 1.2.8 Photo AI - how to make main window empty and ready after processing and saving image?

The new 1.2.8 version no longer has a close button flyout in the lower left after clicking on the main “close window” button after a process is completed and the image saved. How does one now make the main window empty and and available to drag a new image? Thanks!

File close or Ctrl-W on windows, not sure on Mac. If you are on Mac it will show the shortcut next to the command.

I am on a Mac. I now see where it happens. The three vertical dots within the image icon at the lower left corner. Thanks.
