To join a group (class) you need a access code by the group maker (teacher). Under "Join group" you can enter the access code to get the group info.
If it finds the appropriate group, it shows who the administrator is and which ebooks contain shared content.
Now you can join the group. The groups are displayed in a list. After joining, the teacher must confirm the membership. As long as the status is set to "open" and then switches to "joined".
The information about the group can be viewed at any time by clicking on the list entry. There the ebooks with shared content are listed and the information about the group producer.
The shared contact will automatically appear in the corresponding ebooks.
