A network node for handling access to sharing media in a media session in an Over The Top (OTT) Digital Assistant (DA). The media shall be shared between a first participant A and a second participant B in a communications network. The first participant A has access to sharing media in the media session in the OTT DA. The network node receives a request for access from the OTT DA. The request for access relates to the first participant A requesting access for the second participant B to sharing media in the media session in the OTT DA. The network node forwards the request to an IP Multimedia Subsystem (IMS) node in the communications network, to trigger the IMS node to switch on the sharing of media in the media session in the OTT DA for the second participant B, when authorised by the participant B.
