I'm creating a travel app for personal use with friends and family. I'm a beginner at app development and I created an AI-powered interface in Canva so that after the user enters the app, they are directed to the user selection tab, but I'm having problems. I want to use the real photos of the users that I already have with a white border, and when the user selects someone, I want it to show an extra blue border to indicate that they were selected, but I don't know how to do that.
