How to close modal interstitial?

i need to test this website (mobile version) , but i need to close the modal interstitial and have a “first view only” result in the video (if i use first view and repeat, in the repeat video the interstitial obviously disappears but loading time isn’t the one that i want to show).

I tried with script like

sendClickAndWait class=“enjoy” // class of the button

but it doesn’t work. I’m a beginner with script so i believe that i make some mistakes, suggestion?
