        return_type="tuple[bool, Any]",

Message is the string passed to pycmd().

For messages you don't want to handle, return 'handled' unchanged.

If you handle a message and don't want it passed to the original
bridge command handler, return (True, None).

If you want to pass a value to pycmd's result callback, you can
return it with (True, some_value).

Context is the instance that was passed to set_bridge_command().
It can be inspected to check which screen this hook is firing
in, and to get a reference to the screen. For example, if your
code wishes to function only in the review screen, you could do:

            if not isinstance(context, aqt.reviewer.Reviewer):
                # not reviewer, pass on message
                return handled

            if message == "my-mark-action":
                # our message, call onMark() on the reviewer instance
                context.onMark()
                # and don't pass message to other handlers
                return (True, None)
            else:
                # some other command, pass it on
