Out of curiosity, I tried running Orca on niri, and apparently it sort-of works for some apps (I expected nothing to work at all; idk anything about screen readers). However, compared to GNOME Shell, there's quite a few missing or broken things. I documented what I found here: https://github.com/YaLTeR/niri/issues/1904
Is there some "Integrating Orca to Wayland desktops" docs? Like, what the compositor needs to do, who handles the hotkeys and how, etc.
(not actively working on this, just curious)
