Hi,

Is it possible to select the tab from child page inside a tab. e.g

3 tabs in Root (Tab1, Tab2, Tab3)

Page Stack in Tab1 is : Tab1 > View A > View B > Goto Tab3

I tried looking into documentation couldn't find anything for Prism.MAUI. I created the tabs like this.

/TabbedPage?createTab=NavigationPage|Tab1&createTab=NavigationPage|Tab2&createTab=NavigationPage|Tab3
Is it possible to select Tab3 from View B?

"selectedTab=Tab3" is not working. I am getting the below exception when trying it.
