Use the :filter-forced-window hook for this:

(:add-hook (in jwno/context :hook-manager) :filter-forced-window
   (fn [_hwnd _uia exe _desktop]
     (string/has-suffix? "\\SomeNaughtyExecutable.exe" exe)))

Here we are checking a window's exe file path, to see if we should force it.

To determine if a window is suitable for forced management, you can invoke the :manage-window command on it, and see how it reacts. This command is bound to Win + W M in the example config.

The :filter-forced-window hook will override the :filter-window hook.
