Does anyone know what extension is this?

I just moved to new PC and I forgot to make a list of extensions when making backup. Now I can't find this particular extension which allows you to have dock items on top bar (it can show pinned items as well but I had it disabled)

It's GNOME 49 / Fedora 43 so the extension is very likely still being maintained. The extension also has Windows 11 like click/minimize animations.
