Power BI embedded report doesn't load visual's data

It was not this.

I tried another alternative and downloaded PowerBI desktop. I created a report there with my Kusto DB from Fabric as a source and published it on Fabric at the end. After that, on the Fabric Platform, in PowerBI settings, at the category of Semantic Models I choose my report and went to Data Source Credentials and I had to resign-in (having the Privacy level set to None). After this it worked. 

I did the steps from PowerBI settings before too, the privacy levels were the same, but when the report was created on Fabric I could not get it to load the data when embedded, only when I created it using the desktop version of PowerBI.
