What security and privacy features can I set up when using zoom scheduler?

I have a new zoom scheduler subscription and I'm setting up a schedule there, so that I can give one-to-one sessions to clients.   I am having trouble finding information on how zoom scheduler keeps meetings secure and private, what meeting features will be enabled/not enabled by the scheduler automatically, and how I can customize any security/privacy features?    For example, I'd like to offer a complimentary short chat with potential clients to help them evaluate whether they'd like to work with me.  How can I safely offer this without this offer being open to misuse?  Thank you!
