When scheduling a session, users have the option to add links if such a session is going to be held online.
To do so, click on Schedule a session of the Course. From there, you can select the location (if it is going to be held at a physical place) or else you can turn on the ''Is Online'' switch and input the link to the session in the location field.
The session link will then appear both in the email invitation which the employees receive, as well as on their calendar if they add the session to their Outlook/Gmail calendar.
