* <as> : String Array

Exceptions are the names of the Java Exceptions returned in the body field. They typically contain an additional message with details. All Exceptions begin with "org.asamk.Signal.Error." which is omitted here for better readability.
Phone numbers always have the format +<countrycode><regional number>
== Methods
=== Control methods
These methods are available if the daemon is started anonymously (without an explicit `-u USERNAME`).
Requests are sent to `/org/asamk/Signal`; requests related to individual accounts are sent to
`/org/asamk/Signal/_441234567890` where the + dialing code is replaced by an underscore (_).
Only `version()` is activated in single-user mode; the rest are disabled.
updateGroup(groupId<ay>, newName<s>, members<as>, avatar<s>) -> groupId<ay>::
* groupId : Byte array representing the internal group identifier
* newName : New name of group (empty if unchanged)
* members : String array of new members to be invited to group
* avatar : Filename of avatar picture to be set for group (empty if none)
link() -> deviceLinkUri<s>::
link(newDeviceName<s>) -> deviceLinkUri<s>::
* newDeviceName : Name to give new device (defaults to "cli" if no name is given)
* deviceLinkUri : URI of newly linked device
Exceptions: AttachmentInvalid, Failure, InvalidNumber, GroupNotFound
Returns a URI of the form "tsdevice:/?uuid=...". This can be piped to a QR encoder to create a display that
can be captured by a Signal smartphone client. For example:
updateProfile(newName<s>, about <s>, aboutEmoji <s>, avatar<s>, remove<b>) -> <>::
* newName : New name for your own profile (empty if unchanged)
* about : About message for profile (empty if unchanged)
* aboutEmoji : Emoji for profile (empty if unchanged)
* avatar : Filename of avatar picture for profile (empty if unchanged)
* remove : Set to 1 if the existing avatar picture should be removed
