PowerBI Embedded service filtering with Dynamics Portal

Hello,

I'm setting up a Dynamics Portal and trying filter an embedded PowerBI report. It seems to be possible when you read this documentation. 

Extract : "While embedding the Power BI content, customizers can use filter parameters to create personalized views."

But in my Portal I have the following liquid tag :

{% powerbi authentication_type:"powerbiembedded" path:"https://app.powerbi.com/groups/xxxxx-xxxx-xxxx-xxxx-xxxxx/reports/xxxxx-xxxx-xxxx-xxxx-xxxxx/ReportSection?filter=Contact/emailaddress1 eq '[email protected]'" %}

Of course, considering the email exists in my Data Source. If I open the URL in a browser, the filter is applied.

The iframe just remove the filters so filters aren't applied.

If I try to set the iframe src with JS, I have an error saying the set parameters isn't allowed in iframe. Anyway this is not what I want as this service should do the job.

Any suggestion/help ?

Thanks
