How to wait until navigator.notification.prompt() input has been given

I am using a Cordova app to embed a React app. In a certain point, the user connects to the camera and a notification appears when a QR code is detected. I want that the code execution waits until user has entered his/her answer “Yes/No”, but I can’t get it to work. Notification prompt message works as expected though.

I need it to pause somehow, as in an async function (like prompt would, for instance). How could I pause the code execution until the user has chosen Yes/No in screen? I guess with some async/await but don’t see where… I have tried unsuccessfully so far:

let test = null;
let input2 = null;
notification = navigator.notification.prompt("Do you know this QR code?",
     async function(input) {
     input2 = input;
     test = await NotificationFunction(input, Camera_content);
     console.log(test)
     console.log('input2')
     return [test, input2]
     });

let test2= await notification
console.log(test2)
console.log(notification)
console.log(await test)

Thanks a lot in advance!
