Is there anyway to add widget to Screen outside compose function?

[MuongKimhong]

As far as i know, we can add widget to screen in compose function with yield keyword. Is there anyway to add widget outside compose function? For example,

class MyScreen(Screen):
    def compose(self):
        yield SomeWidget()

    def on_some_event(self):
        # add some widget
        yield SomeWidget() # this is not working 

For remove, we can do self.query_one(SomeWidget).remove()

Perhaps a quick revisit to the tutorial is in order, there's a section about that.
