Identify AMP page when appearing as Google My Business Website Results

### Description

Hi, I use AMP for my clients since 2018 and having over 70 running sites using AMP
I face slow loading issue when website results appear as Google My Business Result
this is because it includes a redirect to amp version after user click on "website" button of Google My Business result because it has Desktop version of the website then once user open it, Server redirect to /amp/ version
here there are 2 item that increase loading time on mobile:
1- The redirect from desktop version to /amp/ ( it can be solved by letting Google My Business use amp version of the website url in "Website" button
2- Power of preloading AMP results is not live currently for Google My Business results so now, AMP site doesn't load instantly like it load for if website is found in normal Google search results

### Alternatives Considered

I don't have alternative solution unfortunately because this happen within Google My Business search result

### Additional Context

The report names no source file, test, or entry point. Start by determining whether AMP controls the Google My Business Website URL or the redirect, then verify whether a reproducible project-side change is possible and document the result.
