I aim to establish a restricted webinar, where users request access via [this](https://developers.zoom.us/docs/api/rest/reference/zoom-api/methods/#operation/meetingRegistrantCreate) API. Despite generating a JWT token from [this](https://developers.zoom.us/docs/meeting-sdk/auth/#generate-a-meeting-sdk-jwt) page, the API consistently responds with an “invalid JWT token” error.\*
