Using a mouse to close apps in IOS 15

I couldn't find an answer anywhere how to use the mouse to close apps in IOS 15, except someone else asking the question and it being unanswered. I figured it out through trial and error, so I thought I would post it in case others have the problem in the future.

Hold down on the middle mouse (scroll wheel) button while swiping the tile upward with the mouse like you would normally do with your finger using touch to close an app.

Simple, once you figure it out. Not sure why this seems difficult to find the answer to or why the question went unanswered by support earlier. I will caveat that this works on my Logitech Pebble M350 mouse, and I haven't tested any other mouse, but I expect it will likely work with most all mouses that have a middle scroll wheel with a button.
