I am using Jitsi Meet for video call in one of projects of mine. I cloned the project using link https://github.com/jitsi/jitsi-meet and connected with my react app and is working well.Now I want to change the UI of jitsi meet ,for this purpose I went to documentation ,I followed the steps of i changed into interface.config.js file and title.html file but they are not changed ,so then i build it using “make source-package ” it gives me error:
