Short Answer: We don't know
Long Answer: You are asking about a Feature within Power BI and availability of that Power BI Feature in other environments. Unfortunately, the Microsoft Maps Team does not have visibility into Power BI availability or offerings so I would recommend asking the Power BI team as they control their codebase and offerings.
Note that their forums are also searchable such as https://community.fabric.microsoft.com/t5/forums/searchpage/tab/message?advanced=false&allow_punctuation=false&filter=location&location=category:powerbi&q=GCC
