Hi "Living Trial",
Please see previous posts on the same topic such as https://learn.microsoft.com/en-us/answers/questions/2244961/how-do-i-setup-azure-maps-to-get-sharepoint-online?page=0&orderby=Helpful&translated=false#answers. You are correct, you likely need Sharepoint Support to update their guidance on maps integration as I am only finding Bing Maps too.
Sincerely,
IoTGirl
