Power Point live data for External users problem

Greetings, 

I've embeded some of PBI data into Power Point and I'd like to share it with an external user. 

Based on my understanding, in order for the external user to access this data, he'd need PBI account? Is there some kind of a solution, that would enable me to make this data publicly available as I can can do with the report itself?

Thank you very much for responses. Wish everyone happy holidays!
