Members can be invited to a class via a "class code".
Class codes have an expiration date and are only valid for "30 days" from the time of issuance.
Expired codes cannot be used, so please check the remaining period before sharing.
■ How to invite members
Log in with the class manager account → Class → [Invite members] → Share the class code
※ Admin can directly copy and share the code. You can also check the remaining validity period and reissue (code renewal).
