Embedded PowerApps OnStart and PowerBIIntegration.data

Hi Team,

I have created a PowerApps from PowerBI and pass some data to it.

i put a galery into the canvas and I can see the received data.

I have to transform the data so I put some Set() and ClearCollect() into the OnStart section but the created variables are empty.

When I open the PowerApps from the PowerBI i am able to run the OnStart and all variables populated as I except but when I open the PowerBI report and the PowerApps visaul started the variables are empty.

Do I miss some application setup?

Do I except corretly that I should be able to use PowerBIIntegration.data in the OnStart functions to create variables?
