Connect to new room from conference view

Hello guys,
I am working on a react native app which is basically a fork of the official jitsi meet repo, where I plugged my own screens and logics and made few customizations on welcome and conference layout.
Now I need to add a button on the conference screen, and when I click it I need to connect to a new room.
Given that I can add the button by myself, how can I join a completely new room by clicking on that button?
Many thanks in advance
