On macOS (at least Tahoe), native keyboard shortcuts for window tiling are supported by most applications. For example, when a user hits `Fn + Control + ← (Left Arrow)` on the keyboard, the current window is positioned at the left edge of the screen. Another way to have the same positioning, is to drag the window (using a mouse or trackpad) towards the left edge of the screen. Whereas the latter works with the native Proton Mail app (not Browser), the former does not.
Please make sure that the keyboard shortcuts for window tiling are supported for the native Proton Mail app.
