Procedure to get the Host's consent for scheduling zoom meeting for them

Hello everyone!
We have a project where we are building a medical app, for the doctors and the patients, where each doctor will have their own Zoom account.
Using our app’s calendar functionality , the patients will be able book appointments with the doctors. So we want to integrate our app with Zoom account of the doctors.
I assume we need a consent to generate the authorization token, so how can the doctors provide a consent to schedule Zoom meetings and automatically generate the Zoom meeting links on behalf for doctors zoom accounts from our application back-end. Please advice.
