ArrowChat and OpenTalk RTC intergration

Hi there. we have an arrowchat integration on our website ([login to view URL]) which is PHP built chat platform. The app comes with different integration options. We have chosen to integrate with OpenTalk. We a few chatroom customizations. 1. 2 Buttons One for instantiating multi party audio chat another one for instantiating multi party video chat 2. Can we possibly by pass the need to for members to accept invite such that everyone in the chatroom is automatically redirected and logged into the audio and video chat rooms respectively 3. Bypass mic check for audio and camera check for video (the chat platform is for an NGO platform that deals with elderly people so we just need to eliminate as many clicks and checks as possible)
