Google Maps - RefererDeniedMapError

[LeDahu22]

Describe the bug
Using our own Google API Key, we are unable to use Google Maps component because of the following error (in the browser console) :

Google Maps JavaScript API error: RefererDeniedMapError
https://developers.google.com/maps/documentation/javascript/error-messages#referer-denied-map-error

After contacting Google API team, we received the following explanation :

I can confirm that the domain *********.fr has been blocked by our Compliance team. The block is due to an Attribution Violation, specifically that the Google logo or required copyright notices are missing from the map display.

To resolve this issue and have the restriction reviewed, please follow these steps:
• Correct the Violation: Ensure that the Google logo and all required copyright notices are clearly visible on your map. You can review our attribution requirements here: Google Maps Platform Attribution Guidelines. Please let us know when you apply the changes to the attribution.
• Submit an Appeal: Once the fix is implemented, please submit a formal appeal to the Compliance team using this form: Maps API Compliance Appeal Form.
Please note that the Compliance team reviews appeals in the order they are received, and the average response time is 1 to 2 weeks. You will receive an update directly from them once their review is complete.

Expected behavior
The component should implement and show informations expected by Google.
