Private Community Groups?

First of all, thank you moomoo for making so many upgrades and being user centric. I really like the moomoo games and also leaderboard features that allow me to learn and have a "friendly" comparison with fellow users. wondering if it's possible to form private chat groups in Moomoo? I have several investor WhatsApp groups so wondering if we can likewise form something similar in Moomoo make it easier to share more moomoo features like charts or news articles instead of screenshots. not sure if the feature is already available as maybe I'm not aware but yep would love to have a private group for more in depth discussion. just my 2 cents worth of an idea, tks moomoo team and merry Christmas everyone! wishing everyone health and wealth in the coming year!
