What I have done and why
When users open the search in the Interest screen and search for a non-existing item, they can navigate back to the Interest screen by clicking on "Interests" in the Search screen. Before that Interests was navigating back to the interest screen

I used popBackStack() function in onInterestClick(). This will navigate back by removing the search screen from the back of the stack and then navigation to the Interest screen.
