How to check XHR that sends to get dynamic content in browser?

Question

I need to check which XmlHttpRequests sends to display dynamic data on this site do the scraping in Python

I've been informed that request to this API source is send

In Firefox I do

• click on Inspect element on the first site above
• click on the Network tab.
• select XHR

But the JSON request did not appear. Nothing appears. Even pressing F5 or clearing the cache

Please, can it be some wrong configuration in my browser / dev console that does not allow displaying the XHR list? Or is there any way to do this?
