I implemented a video call using Twilio by react
as frontend and Ruby on Rails
as backend.
now I wanna add screen-sharing on that.
Have I to change my backend code?
How to add a screen-sharing feature on a video call?
When I enable screen sharing in video calling, does my call change to an audio call automatically?

I don't believe you need to change your back end code for this. For the front end, I would recommend checking out this blog post: Screen Sharing with JavaScript and Twilio Programmable Video (the back end for this is Python, but it shouldn't matter).
