Power BI Power apps and Google cloud platform

Hello everyone,
I'm looking to create a mini application in Power apps inside a Power BI report to modify data coming from Google Cloud platform SDDS. I manage to connect my live query data, to publish my report, to have the Power Apps application with the PowerBIIntegration data. But I can't patch. And when I look for the data in the patch, it finds nothing. is there something special to configure to patch on google cloud platform SDDS and if so how? Do I have to add my data source in the power apps application when I have powerbiintegration? Thank you very much, Jim
