How i can Create the "Purview Hub (automatically generated)" ?

Hi PA_DA ,

To access the hub, open the Fabric settings pane and choose Microsoft Purview hub.When you select the Microsoft Purview hub option, the hub opens to the view that is appropriate for you, and insights are generated. If this is the first time insights are being generated, it might take some time for them to appear.

For more you may refer to：

The Microsoft Purview hub in Microsoft Fabric - Microsoft Fabric | Microsoft Learn
