Every modern web browser comes with a special suite of tools for web developers called the Developer Tools (or devtools for short).
This suite contains a lot of powerful tools used in web scraper development that can help to debug and understand how the target websites work.

The "Network" tab (aka the Network Inspector) can be used to inspect the network traffic of the page. This can be used to understand how the website works and discover its backend and hidden APIs:
One of the most popular features of Network devtools is the ability to export the requests to cURL commands (right click -> copy as curl) that can be converted to scraping code using the cURL to Python tool.
