I'm submitting an app I made using React Native and Expo to the App Store. Got the build in a .ipa file and uploaded it to Transporter and had it sent to App Store Connect. The last app I built and submitted was a Unity game and I used Xcode to send it to App Store Connect. Using Xcode, there was the area where I put in the app icon in all the different sizes (20px, 29px, 76px, etc). On Transporter, the app is just sent to App Store Connect. How do I add app icons through Transporter or can I get the app on Xcode to add the icons?

You should ask the question to React Native first.
