I have a WebView which is displaying a Bank form to enter OTP. For Some banks, an input field to enter OTP comes on TOP and for other it comes at the bottom, etc.

I want to zoom my WebView to the input field. One thing to point is that the input field is always the first input field of the page. Hence I can an instance of it by executing the JS as shown below:

document.getElementsByTagName('INPUT')[0]

Now I want WebView to zoom to it. Can someone pls help me with how to do it?
