Remove Jitsi Text 'connecting to your meeting' and when call initiated its on speaker Mode I want to on EarPiece Mode

Jitsi team ,
I making a call app in kotlin using jitsi and I successfully implemented it but I want some change when call comes and it connects then at the connecting time here shows 'connecting to your meeting '.I also attach an image of this ,and one more thing by default I want my call on Earpiece but still by default it goes on Speaker mode.
Please help us for solving these issues!. Still I am using
implementation(‘org.jitsi.react:jitsi-meet-sdk:3.8.0’) { transitive = true }

You can do that if you are working in source code.

Which file can I edit this in?
