As a result, generally the answer to 'how do I do X in wayland' is 'you don't. here's how you do it in KDE, here's the extension you need to install in GNOME to be able to do it, and you're rolling the dice on any other DE'. And that's as a developer, if you're a user there's a good chance the developer has gone 'fuck it, I'm sticking with X11'.
(This fragmentation is even worse when it comes to configuration. e.g. for something like graphics tablets, where there is a relatively complex configuration of how the features on the hardware map to delivered input events, it's left up the the compositor to handle how that's configured. Which means that there's basically no standard way for you to configure your tablet, and there's no complete option: you are either forced into GNOME or KDE because you need some option one supports and the other doesn't, and if you're on a smaller one, you have basically no chance. X11's architecture meant this tended to be much more standardised, and while each DE had its own UI for configuring an input device, you could in practice always fall back to another tool, even if it was usually an arcance CLI, to get what you want.)
