In Kotlin you can achieve this by adding setOnKeyListener to your WebView. This listener responds to clicks on the device's hardware buttons.

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    val myWebView: WebView = view.findViewById(R.id.your_webView)
    myWebView.webViewClient = WebViewClient()
    myWebView.loadUrl("https://www.google.com/")
    myWebView.setOnKeyListener { v, keyCode, event ->
        if (keyCode == KeyEvent.KEYCODE_BACK && myWebView.canGoBack()) {
            myWebView.goBack() // Navigate back to previous web page if there is one
            nested_scroll.scrollTo(0, 0) // Scroll webview back to top of previous page
        }
        true
    }
}
