Dataflow folder is empty in Power BI Desktop

I am testing Dataflow process, and for this purpose I have created Dataflow in "Power BI Service" successfully, which imports the data from my local SQL server. But when I try to consume this Dataflow in Power BI desktop, it shows me empty folder.

I am using same Power BI account for creating Dataflow and in Power BI desktop. Is there any step which I am missing?

Please note that I am using Power BI pro (trial version), is there any limitation with this account type?

Thanks
