create actionbar within screen that plays video

[Gorashy]

I have screen that plays video. the video plays but there no option to return back when the video finishes playing. I want
to create a button to go back and other 2 button for another purpose or an actionbar with three items. please explain in details

def playingv(self):
        
        print(theoption3)
        
        if theoption3 == str('imperative sentences to passive voice',).strip("()"):
            video= VideoPlayer()
            
            self.add_widget(video)
            
            video.source='can.mp4'
            video.state='play'
            video.allow_fullscreen
            video.fullscreen=True
            video.options={'eos':'loop'}
            
        elif theoption3 == str('would you mind',).strip("()"):
            video= VideoPlayer()
            
            self.add_widget(video)
            
            video.source='adjectives.mp4'
            video.state='play'
            video.allow_fullscreen=True
            video.fullscreen=True
            video.options={'eos':'loop'}
