Google Photos

So, I’ve got two Win 10 desktops, both up to date. On one I have an app pinned to the toolbar with the Google Photos icon, and of course it opens an instance of Google Photos in a web app wrapped in what I think is a UWP, although I don’t see a UWP app in the “all apps” view, nor is there such an app in the Windows Store.

Can anyone tell me how to get this useful pin onto the taskbar of my other desktop?

I know it sounds like a stupid question, but I just can’t figure it out…

Thanks in advance. miker
