I need to edit Flussonic WebRTC Embed Player Tweaks

I'm looking for a professional with experience in editing the Flussonic WebRTC embed player. Specifically, I need changes made to the controls and buttons.

I need to edit Flussonic embed player on website.
It is muted when page is being loaded. Player plays automatically but audio is muted and I need to unmute it. I want it to be unmuted when loading.
