Not passing "impersonate"

If I don't pass any impersonate argument in the request, what does it do by default?

The you got standard curl headers:

>>> from curl_cffi import requests                                  
>>> print(requests.get("https://httpbin.org/headers").text)         
{                                                                   
  "headers": {
