How to do auto update of the "Variable display" tile in the Application designer

I am using the project variables to be displayed in the "Variable display" tile, Even after updating the project variables, "variable display" tile is not displaying the updated values of those project variables. I need to explicitly refresh the browser to see the "Variable display" tile to display the latest values.

How to do the auto updation of the "Variable display" in the App designer instead of explicitly refreshing the browser ?
