How can I export Attendee list from Microsoft Teams Live events session using Microsoft Graph API?

Hello Microsoft Teams specialist in using APIs, I wish you all are safe and healthy!

All of us are facing an immeasurable COVID-19 pandemic and working remotely is the current guideline here at the company as well as a lot of other companies in the globe, indeed, face-to-face courses must now be taken remotely keeping all employees safe, so, I am asking you some helping in: How can I use Microsoft Graph APIs to extract a attendee list from a live session from Microsoft Teams?

We are hard working to try to use the Microsoft Graph in order to get the Attendee data from a Live session in order to import them into SAP SuccessFactos LMS as a virtual learning session attendees based on API economy connectors (rest).

Do you know how can I extract the callRecord ID (highlighted in bold) from the joinWebUrl in order to use the API method GET https://graph.microsoft.com/beta/communications/callRecords/{id} ?

If you have any tips to extract the live session ID or other way to export the “AttendeeReport.csv” dynamic/automatic, it will be awesome to advance on our pilot 😐

I research based on this blog https://tomtalks.blog/2020/03/microsoft-teams-call-records-and-session-details-api-public-preview/
