Choose an Activity name, such as “Week x readings”.
Note: Embedding a reading list in Moodle can potentially cause some access issues in different browser.
A solution would be to change the display of the reading list to open in a new tab/existing window which will avoid the authentication problem for all users.
To do this, In the settings page, under General, click Show more… to view more settings.
Change the Launch container to New window and/or Existing window.
Then click Save and display.
