locked-one-to-one-rooms - One-to-one conversations are now locked to the users. Neither guests nor other participants can be added, so the options to do that should be hidden as well. Also a user can only leave a one-to-one conversation (not delete). It will be deleted when the other participant left too. If the other participant posts a new chat message or starts a call, the left-participant will be re-added.
read-only-rooms - Conversations can be in read-only mode which means people can not do calls or write chat messages.
config => attachments => allowed - Whether the user can upload files into a chat
config => attachments => folder - User defined folder where items should be uploaded to
config => conversations => can-create - Whether the user can create public and group conversations, if not only one-to-one conversations are allowed
force-mute - "forceMute" signaling messages can be sent to mute other participants.
conversation-v2 - ~~The conversations API v2 is less load heavy and should be used by clients when available. Check the difference in the Conversation API documentation.~~ Replaced by API v4 when conversation-v4 is set.
chat-reference-id - an optional referenceId can be sent with a chat message to be able to identify it in parallel get requests to earlier fade out a temporary message
conversation-v3 - ~~Whether conversations API v3 is available~~ Replaced by API v4 when conversation-v4 is set.
sip-support - Whether SIP can be configured and enabled by moderators. The conversations API will come with some new values sipEnabled which signals whether this conversation has SIP configured as well as canEnableSIP to see if a user can enable it. When it is enabled attendeePin will contain the unique dial-in code for this user.
chat-read-status - On conversation API v3 and the chat API the last common read message is exposed which can be used to update the "read status" flag of own chat messages. The info should be shown only when the user also shares their read status. The user's value can be found in config => chat => read-privacy.
listable-rooms - Conversations can searched for even when not joined. A "listable" attribute set on rooms defines the scope of who can find it.

conversation-v4 - Whether conversations API v4 is available. This also means that v1, v2 and v3 are not available anymore. The changes on API v4 allow a user to have multiple sessions in the same conversation on different devices which is incompatible with the data structure that was used by the previous APIs.
