basically I want this splitview from MainPageView to load the departmentView which contains its own ViewModel that has an Observablecollection
<SplitView.Pane> <Frame> <local:DepartmentsView/> </Frame> </SplitView.Pane>
but it has to be in sync with the navigation service. because I am relying on the template10's OnNavigatedToAsync to load my data
