Open your map and click on the three dots in the top right corner.

Select "Copy" in the dropdown and click "Distribute to Group" in the dialog that opens.

Select the desired class or group in the dropdown and confirm.

A separate copy of the map is then created automatically for every member of the group.

Click "Open Folder" to go directly to the newly created folder containing all map copies.

Each copied map carries the name of the recipient (student) in the map title.
