So, I tried that, and it sorta works but there's something odd. I wind up with one thing in the notification area that switches layouts correctly (it's colored white), and one which is colored blue, doesn't work to switch layouts, and keeps popping upa right-click menu without me right-clicking on it.
Did you install ibus-qt5 and update ibus in the copr repo? and you need to run a QT application with QT_IM_MODULE=ibuswayland and could switch layouts with the focused QT application.
