amp-onetap-google not working

## What's the issue?

I am trying to implement one tap login ([https://amp.dev/documentation/components/amp-onetap-google/](https://amp.dev/documentation/components/amp-onetap-google/)) on my amp page. It is supposed to show a pop-up prompting the user to login with Google Account.

The popup does not show up and I see the following error in the console (Chrome)
`Refused to display 'https://accounts.google.com/o/oauth2/auth?client_id=99199563698-renu0s9sdukir1ijij853r3eovj5fre3.apps.googleusercontent.com&redirect_uri=http://localhost:8000/google-oauth2/complete/google-oauth2/&state=qn3mfmfBf5I3ejWMNmI21XMdsQdpUlqI&response_type=code&scope=https://www.googleapis.com/auth/userinfo.email+https://www.googleapis.com/auth/userinfo.profile' in a frame because it set 'X-Frame-Options' to 'deny'.`

## What browsers are affected?

Checked on Chrome and Firefox and both are affected

## Which AMP version is affected?

AMP version: 2101300534005

Start by reproducing the behavior at https://developer.paralleldesk.com/amp/techniciancadet-c with amp-onetap-google, then compare the result with the component documentation. Inspect the Chrome and Firefox console errors and the affected AMP version; done means the Google One Tap login prompt appears without the reported frame error.
