you got reply from pooja

Like, Android.ShowToast('Hello! Pooja here.')
Now internally it will call an event of extension where you can choose what you want to do next.

I don’t think it is impossible, but it is not easy. You won’t find a tutorial to do it or solve it by yourself just with a few blocks.
To get an idea on how it works, see this:
This is and old topic and it is how the websites could make it work. You as a browser developer would have to make your browser work with the websites’s code.
