How do you change the "Display Name" of a React Native app in XCode?

I have a React Native app that has Display Name theApp:

I want to change it to The App. However, I'm hesitant to just change it in that box in XCode because there are now instances of theApp elsewhere in the autogenerated code, and in the Bundle Identifier etc.

Has anyone changed a Display Name like this before? Do you know how I should approach it?
