PowerBI title into PowerAPPS

Hi there, just a quick question before going deeper with PowerBI:

I have my PowerAPP connected with my sharepoint point and shared with the users in my organization, so far so good, everything works perfect.

Now I was in a skype meeting with other people talking about PowerBI, so I've decided to add some titles to my APP, in my screen I can see the Powerapp working fine, but none of my coworkers can see the powerBI titles, it says something like the title was removed or you don't have permission to access it. etc.

Could someone provide an answer? 

Do I need to buy the PRO version to do this?

Thanks in advance

Regards
