Does anyone know how to set a QQ group prompt like "This group is full, please add two groups ..."?

Group introduction. This group is full, please add two groups of XXXXX. . . Or directly change the group name of your slow group to this group is full, please add two groups XXXXXXX. This works well. . If the group profile is specified, the computer can't find the group profile. . You can only see it when the mobile phone is looking for a group. Recommend the second method.
