Direct messages are treated as a special form of a team, and are sent in individual channels, restricted to two users. Calling the context /api/cowork/teams/directmessages lists all open direct message channels of the user. The response is analogous to the channels request. Messages of a channel are requested using the regular messages request API.

Direct message channels remain persisted until both members have left the channel.

Returns a list of direct message channels available to the user in the following form:

[
    {
        "channelId":   "<ID of the channel>",
        "teamId":      "<ID of the channel>",
        "displayName": "<Name of the channel>",
        "description": "<Description of the channel>"
    },
    ...
]
