On your Dashboard
As soon as you log in you will see your Online meeting room URL at top of the page underneath your picture. You can click the "View meeting room details" button on the left to see all of your conference details, including dial-in number, access code, moderator PIN, and more.
Under the Menu tab
You can also find your conference details by going to 'Menu' > 'Meeting details'. This page shows more information than the page on your dashboard, showing you moderator controls, the list of dial-in numbers, and other information along with your meeting room details.
