React native UI

I’m trying to modify the UI of the conference for a mobile app, more precisely the WaitForOwnerDialog.native.js.
After the changes, I run make on my jitsi installation, but when I connect with the app the UI is not updated.
Did I miss something?

PS: I’m new to react-native

I am trying to do a similar thing but on Native Android. For my situation, I have to modify the react native code and then build the SDK and then integrate it. Are you building the app completely in React Native ?
