+This command should only be used if this is the primary device.
+
+Exceptions: Failure
+
+sendSyncRequest() -> <>::
+
+Sends a synchronization request to the primary device (for group, contacts, ...).
+Only works if sent from a secondary device.

+Exceptions: Failure
+
+==== Identity related methods
+
+listIdentities() -> identities<a(oss)>::
+* identities : Array of structs (objectPath, id, name)
+** objectPath : DBusPath representing the identity object path

+Exceptions: Failure
+
+=== Signal.Group interface
+
+The following methods listen to the group's object path, which can be obtained from the listGroups() method and is constructed as follows:
+
+<ACCOUNT_PATH> + "/Groups/" + DBusGroupId
+
+DBusGroupId : groupId in base64 format, with underscore (_) replacing plus (+), equals (=), or slash (/)
+
+Groups have the following (case-sensitive) properties:
+
+* Id<ay> (read-only) : Byte array representing the internal group identifier
+* Name<s> : Display name of the group
+* Description<s> : Description of the group
+* Avatar<s> (write-only) : Filename of the avatar
+* IsBlocked<b> : true=member will not receive group messages; false=not blocked
+* IsMember<b> (read-only) : always true (object path exists only for group members)
+* IsAdmin<b> (read-only) : true=member has admin privileges; false=not admin
+* MessageExpirationTimer<i> : int32 representing message expiration time for group
+* Members<as> (read-only) : String array of group members' phone numbers
+* PendingMembers<as> (read-only) : String array of pending members' phone numbers
+* RequestingMembers<as> (read-only) : String array of requesting members' phone numbers
+* Admins<as> (read-only) : String array of admins' phone numbers
+* PermissionAddMember<s> : String representing who has permission to add members *ONLY_ADMINS, EVERY_MEMBER*
+* PermissionEditDetails<s> : String representing who may edit group details *ONLY_ADMINS, EVERY_MEMBER*
+* PermissionSendMessage<s> : String representing who post messages to group *ONLY_ADMINS, EVERY_MEMBER* (note that ONLY_ADMINS is equivalent to IsAnnouncementGroup)
+* GroupInviteLink<s> (read-only) : String of the invitation link (starts with https://signal.group/#)
+
+To get a property, use (replacing `--session` with `--system` if needed):
+`dbus-send --session --dest=org.asamk.Signal --print-reply $OBJECT_PATH org.freedesktop.DBus.Properties.Get string:org.asamk.Signal.Group string:$PROPERTY_NAME`
+
+To set a property, use:
+`dbus-send --session --dest=org.asamk.Signal --print-reply $OBJECT_PATH org.freedesktop.DBus.Properties.Set string:org.asamk.Signal.Group string:$PROPERTY_NAME variant:$PROPERTY_TYPE:$PROPERTY_VALUE`
+
+To get all properties, use:
+`dbus-send --session --dest=org.asamk.Signal --print-reply $OBJECT_PATH org.freedesktop.DBus.Properties.GetAll string:org.asamk.Signal.Group`
+
+addAdmins(recipients<as>) -> <>::
+* recipients : String array of phone numbers
+
+Grant admin privileges to recipients.
+
+Exceptions: Failure
+
+addMembers(recipients<as>) -> <>::
+* recipients : String array of phone numbers
+
