NVDA Screen Reader Only reads Title Window in wpf Applicaton and not the whole page

Question

I have created a sample application in wpf(.NET 5.0) which has textblocks.I want my nvda screen reader to readout the text elements as soon as I open my application.I have also set the Automation properties Name. I dont want to change the UX by pressing tabs to navigate between text items and then to focus them. Any help would be appriciated
