Problem to publish to web, maybe an issue with license

[Lazlovlad]

Hello
I have created 2 boards in the PB service:

     I want to use the first (prueba1) as a data repository for a second (prueba2).
The data originates from a SQL server query.

     prueba2 has a directQuery query to the PowerBi dataset of prueba1 .

     It seems the configuration is correct. Within the PowerBI service, prueba2 works correctly, you can see the data and interact with it.
Many attempts are made to publish a website (public), when creating the embed code it does not allow it and does not throw any error or mention.
Apparently it's going to be a privacy issue or permission to use data outside of the PB platform (in SQL) via a second board.
The question is how to configure boards to have access to that board as a unique repository 
and be able to create the public web report of prueba2 or if there is a limitation if the user used in the service in a PRO license?
Thank you for your answer.

Board Prueba1


Board Prueba2


Prueba1 on PB service, SQL Query, external shared activated

Prueba2 on PB service, DirectQuery to prueba1 with PBservice user credentials (Cuenta de Microsoft)
