This may have been provided through chat or in the form of an email invitation similar to the one shown below.

Joining a Meeting
The easiest way to join a Zoom meeting is to use the link provided to you by the librarian, or you can join using the meeting number directly from the Zoom app on your computer or smart device.
If you are joining directly from the app, you can either log into your account, or just click the "Join a Meeting" link and enter your meeting number.
If you are already logged in, you can click the "Join" button and enter the meeting number.
