Hello @Meenambigai!
If you have successfully enrolled in the course, open the Databricks Academy, click on the kebab menu icon (upper left corner), select "My Calendar". You’ll see the courses you’re enrolled in, organized by date. Click on the link and it will navigate you to the course page, where you’ll find the Zoom link.
If the link is still not visible, ensure you’re not trying to join too early before the session's scheduled date.
