Why can't I catch the request (when sending a message on the site)?

Question

Python

There is a site, I'm trying to check its requests.
All requests are found without problems, but when it comes to sending a message to Fiddler, there are no requests.
How can I send a message without browser emulation?
I understand that I would like to see the site, but what are the options for sending?
