How to open specific page only if user is accessing the app for the first time?

Hi,

In my app I know if a user is accessing it for the first time. I want these first-time users to be directed to a specific page after logging in. I’m using Firebase Auth. The flow logic below is not working. Apparently, using the flow function dismiss initial view will open the page as defined in the navigation tab. However, If I don’t use dismiss initial view, it simply won’t load the rest of the app.
