I want to prevent creating conference rooms on the web

Good morning.
I want to build a server with Self-Hosting and use it only with IFrame API.

I want to prevent creating conference rooms on the web.

Is there any way?

jwt authentication

Can jwt limit conference room creation on the web?

When JWT authentication active, only the users who have a valid token can create room. Since the conference will be in your web application, pass a valid token if it’s in iframe

Thank you.

Do I have to set it up separately to use JWT?

Please share the method.
