Roblox voice api

I don’t know if this really applies with scripting but heres my thought:
If there is any API Docs for voice.roblox.com where are they?

I haven’t gotten roblox voice chat in like 3 weeks, and I had everything so I checked the roblox voice chat api and it got showed up for denial reason as seven which I don’t really know what it is because i don’t know where the docs are for that api.
What does that mean?

For the API Docs you should also put /docs after the URL, but even that seems to give no result as all versions are empty.
https://voice.roblox.com/docs
So we really are just left with a single function (inside VoiceChatService).

I looked into the JSON that usually documents all the functions, it had no documentation either so I’m very confused.
