Can't add a Power BI panel

[dunnno]

Hi,

I'd like to be able to add a Power BI panel into my Power Apps app but unfortunately the Dashboard and Panel dropdowns remain greyed out. Looks like it can't find any dashboard.

I was able to add one once, nothing was greed out but now i can't.

I don't know why. The Power BI report is published in my workplace, not in any way private or hidden.
