Please join the function of scanning QR code in discord to join the group!

Hello! I have a good idea to add a function of scanning QR code and adding groups in DC! I am a college student and find that DC has many functions (voice room and chat room! ) It is very convenient for us to discuss assignment (I hate WhatsApp and Google meet, which make me feel extremely inconvenient), and I intend to open a big family (for all teachers and students in the college). Imagine if I put a QR code on the school bulletin board so that interested students can scan the code and join it, isn't it better than putting a link (the link may miss a lot of interested studies) In addition, the chat area of DC is really convenient. I can open chat areas of different subjects and then use the identity group to let the corresponding students join the corresponding subject discussion area. I can also help them discuss assignment in the voice room, thus achieving multiple goals! But the link invitation is really too much trouble! Please be sure to discuss the mechanism of joining QR code into the group! (You have successfully registered the scanned QR code. I believe it is not difficult for you.) Then please!
