**Description**  
Webinar absentees is not returning correct Absentees results

**Error**  
Currently in our system we track attendance to our webinars by checking registrants and compare them to attendees, when the customer is registered in not listed as absentee then it’s considered as attendance. Suddenly we have high rate of attendance reports that are wrong, basically by comparing the absentee API result (which is returning Empty result for webinar {97981012989} occurrence {1637661600000} ) while CSV reports from the dashboard shows only limited number of attendance (less than the number of registrants).

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
JWT using PHP Zoom SDK  
**Which Endpoint/s?**  
The API documented here:

> **[Get webinar absentees - Webinars - Zoom API - API Reference](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarabsentees)**
>
> List absentees of a webinar.
> Scopes: webinar:read:admin webinar:read
> Rate Limit Label: Heavy
> 
> Authorization
> 
> Flow: authorizationCode
> 
> Authorization URL...

**How To Reproduce (If applicable)**  
Try to call this api with values mentioned above and compare the result to the CSV

**Additional context**  
As we said we’re depending on delta between registrants and absentees to know who attended our webinars, is there a more direct way to do this? Probably we can change our implementation even after the bug is checked/fixed.
