how to used CMsgPracticeLobbyCreate create a room for dota2?

[yuanhongguo]

This code can be executed, but there is no callback and it cannot create a game room，I would like to know if kit2 supports creating rooms。

CMsgPracticeLobbyCreate lobbyCreateMsg = new CMsgPracticeLobbyCreate
{
lobby_details=new CMsgPracticeLobbySetDetails
{
game_name = "test_cq_gou",
pass_key = lobbyPassword,
server_region = 2,
game_mode = (uint)DOTA_GameMode.DOTA_GAMEMODE_CUSTOM,
custom_game_id= 2966603798,
allow_cheats = false,
fill_with_bots = false,
visibility = DOTALobbyVisibility.DOTALobbyVisibility_Public
}
};

var requestCreate = new ClientGCMsgProtobuf((uint)EDOTAGCMsg.k_EMsgGCPracticeLobbyCreate);
requestCreate.Body.lobby_details = lobbyCreateMsg.lobby_details;
gameCoordinator.Send(requestCreate, DOTA_APP_ID)
