How can I invite language partners to a group chat?

1. Click on the "Settings" icon in the upper right corner of the group chat to enter the "Chat Settings".   2. Click on the "+" icon in the group member area, and a list will appear, which displays group chat members and your friends. Select the language partner you want to invite to the group.   3. The language partner will receive an invitation to join the group chat. They will be added as soon as they accept the invitation.   4. If the group owner turns on "[Require Approval]", the group owner or administrator must approve their request to join.
