I can confirm that the current version of Power Map does not feature Office 365 integration with Power BI. It is on-premise only for now, and we are planning for Office 365 integration in the future.
In the meantime, you might consider exporting your Power Map tours to video or capturing Power Map scenes and sharing those on your Office 365 site.
I hope this helps!
