Going Back To Mainmenu From Gameover Ui Upon Back Button Press On Device

How to go back to mainmenu from gameover ui upon back button press on device?

 

Put in a navigation button on the game over UI and then connect that button to the the main menu in the game mind map.

 

Thanks Bentforktech. I am sorry but may be I was not clear in asking the question. It is intended for android device button i.e. "back button". I would like to send the player from gameover UI to Mainmenu UI when a user press on-device back button not any button on screen

 

You can use a button that looks like the back button in the way I described. just add the navigation to the UI. The back button takes to back to where you came from. So you can cheat it in your case if you want.
