Hello, nellietheelephant, here is the answer to your question:

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var conversationMember = new AadUserConversationMember
{
        Roles = new List<String>()
        {
                "owner"
        },
        AdditionalData = new Dictionary<string, object>()
        {
                {"email address removed for privacy reasons", "https://graph.microsoft.com/v1.0/users('8b081ef6-4792-4def-b2c9-c363a1bf41d5')"}
        }
};

await graphClient.Teams["{team-id}"].Members
        .Request()
        .AddAsync(conversationMember);
