How to inform leaders to quit the group?

What you should ask is the question in the enterprise WeChat group or WeChat group chat. Sending notifications in group chat requires permission, that is, the owner's permission. You can apply for the group owner to issue a notice, and then @ click on the leader who wants to quit the group to let others know, which is equivalent to issuing a notice. Or you can directly post something in the group chat that leads someone out of the group chat, and then use the permissions of the group owner to @ Everyone, which is also feasible. Or you don't have the management right of the group owner, or you can help the group owner privately. If the leader was originally a group owner, the group owner will move after leaving the group chat. So you can find a new group owner and ask for help.
