If no duration/interval pairs are given, the request indicates that this client has no special needs for GO presence. The first parameter pair gives the preferred duration and interval values in microseconds. If the second pair is included, that indicates which value would be acceptable.
    \note This needs to be issued on a P2P group interface if separate group interfaces are used.
    \bug It would be cleaner to not require .P2PDevice methods to be issued on a group interface. In other words, args['group_object'] could be used to specify the group or this method could be moved to be a .Group PresenceRequest() method.</p>
