on_process_result=SwitchTo

[iBrokeYourGui]

1. This case works fine:
   on_process_result=go_to_main_state,

async def go_to_main_state(_, button: Button, manager: DialogManager):
await manager.switch_to(SettingsDialogSG.main)

2. This case doesn't want to work:
   on_process_result=SwitchTo(Const(""), id="_", state=SettingsDialogSG.main)
   cause:
   Expected type 'Optional[(Union[dict, list, int, str, None], Any, DialogManager) -> Awaitable]', got 'SwitchTo' instead
