Pause game when interstitial ad comes up

Hello, I am trying to pause my game when the interstital ad comes up but it keeps messing with other actions, so came up with this solution and now the pause doesn`t work! Anyone got a better idea??

I haven’t really played with ad implementation so sorry in advance if this is a silly idea.

Could you not have an entire scene dedicated to displaying the ad and when it’s time to display it use the “Pause and start a new scene” event and when the ad is completed use the “Stop and go back to the previous scene” event and let GDevelop handle all the pausing?
