Embed with Sharepoint _ Pricing

Hi All, 

I am working on some Power BI reports that I would like to share through sharepoint within my organization. 

I wonder if every user need to get the Pro Version to be able to see and interact with the report (Not to modify), or is it enough if I work with the Pro version to do the report. Could you please advise?

I have the same question on regard to the Mobile App, does the rest of the users need to have the Pro Version in order to visualize the report on their mobile?

Thanks in advance, 

Regards
