Deep links aren’t meant to navigate within the app from one section to another. They are meant to be a link that you share to others, so they can navigate into the app.
Linking to a screen works differently depending on if you select ‘Show Detail Screen’ or ‘Show New Screen’, and whether or not you pick ‘This Item’ or a specific table, or a relation, etc.
It really depends on what exactly you are trying to do, but in general, I think attempting to use deep links is not the correct approach if you are already inside of the app.
