[Question] Always one on the screen

[sdr0x07b6]

There are many Poppers on one screen that are displayed when a button is pressed.
I would like to display only one Popper for the last button pressed.

Currently, when a Popper is displayed on one screen, if I press a button on another screen, the Popper is displayed at the same time. I have several Poppers displayed at the same time.
How can I close the Popper that is currently displayed when I press down on a displayed area and display it only on the area where I pressed down?
