Google Maps Field - API Key not working for Chromium, does work in Firefox.

Problem/Motivation

I have a drupal 9.2.7 (no other extra modules, standard distribution) site on shared linux hosting using PHP 7.4 via cPanel.

All is working great.

However, one page has an embedded Google Map using Google Map Field module.

If I browse the site using Firefox 93.0 Linux (Gentoo), the site works well.

If I browse the site using Chromium 94.0.4606.71 Linux (Also Gentoo, compiled from source), the map shows up dimmed with the 'Do you own this website?' pop up.

I must have entered my API key correctly, as it is exactly the same site, just different browsers, one works, one doesn't.

I find it hilarious that the Google browser is the one that is not working.

I installed the chrome add-on, which is supposed to validate the API Key usage, but it does nothing that I can see.

Happy to provide additional info, if requested.
