Data Model View is not showing in Live Connection Mode

Even though Power BI documents claim that Data Model View will be displayed in Live Connection Mode , still it is not working for me. I am using the latest (Dec 2020) version of Power BI Desktop. Also I have enabled the Preview Feature "Direct Query for Power BI Datasets and Analysis Services" .

I have also change the setting to local model , none worked for me , I can not see the Diagram view of the model
