how to check button displayed on screen?

Unity Engine
1

Hi,

In my unity game I have a continue button when game over.I need to check if this button is currently displayed on screen (means game over) and show an ad.For some reason before this game over overlay shows my ads are displaying.I want to wait till this game over menu displayed then load interstitial ads to show.

Can anyone give me a pseudo code for this?

Thanks

Pseudocode:

if (gameIsOver)
{
    EnableGameOverButton();
    EnableAdDisplay();
}
