Hi there, @soha95 ...
If your school has opted to purchase paid Zoom licenses to distribute to instructors, then I believe the e-mail address that was used for the Zoom account needs to match the e-mail address tied to your Canvas account. This is also assuming that your school has also set up the Zoom/Canvas LTI external app integration. You may need to have a conversation with your school's local Canvas administrator or someone from your school's Online Learning/eLearning department to figure out how you can get Zoom working within your course. Good luck to you!
