how i can modify header in seleniumwire driver

Question

I want to change my header Http information but nothing happens with the below code. Please help me, what is the problem and how should I solve it? I want to be able to change the user's information on each visit, like the ModHeader extension.

import time 
  import os
  from seleniumwire import webdriver
  from selenium.webdriver.chrome.options import Options  # Import from seleniumwire
  driver = webdriver.Chrome()
  def interceptor(request):
   request.headers['User-Agent'] = 'Mozilla/6.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.63 Safari/537.36'
   request.headers['sec-ch-ua'] = '"Google Chrome";v="93", " Not;A Brand";v="99", "Chromium";v="93"'
   request.headers['sec-ch-ua-mobile'] = '?0'
   request.headers['sec-ch-ua-platform'] = 'os'
driver.request_interceptor = interceptor
driver.get("https://google.com")
for request in driver.requests:
  print(request.headers)
  print(request.response)
time.sleep(500)

my problem like this link in my driver data shows this

The Selenium Wire docs say you must delete first: "If you wish to replace a header, make sure you delete the existing header first with del request.headers['header-name'], otherwise you’ll create a duplicate." — pcalkins, Mar 13 '23 at 23:46

i use this code

from seleniumwire import webdriver  # Import from seleniumwire
import time
# Create a new instance of the Chrome driver (or Firefox)
driver = webdriver.Chrome()

# Create a request interceptor
def interceptor(request):
    #del request.headers['Referer']  # Delete the header first
    del request.headers['sec-ch-ua-mobile']  # Delete the header firs
    request.headers['sec-ch-ua-mobile'] = '?1'

# Set the interceptor on the driver
driver.request_interceptor = interceptor
# All requests will now use 'some_sec' for the user-agent
driver.get('https://httpbin.org/anything')
time.sleep(100)

and i get this answer

  "data": "", 
  "files": {}, 
  "form": {}, 
  "headers": {

    "X-Amzn-Trace-Id": "Root=1-6411d437-6a5b738d424453642abefa89"
  }, 
  "json": null, 
  "method": "GET", 
  "origin": "5.239.189.35", 
  "url": "https://httpbin.org/anything"
}

But unfortunately, there is no change in Google settings. Where does the problem seem to come from?

You just confirmed yourself that it works as intended. The header still is shown different in the network-tab, because it gets changed after the request exits your browser. — kaliiiiiiiii, Mar 15 '23 at 16:53
@kaliiiiiiiii how i can change header like in the photo . i see some chrome extension can change headr http. like RequestInterceptor .but i dont now how i can use this way .this extension have not api so i look up new way in selenium python. or create api for use this extension. i saw ago your question .how you solved this problem? — masoud fallah, Mar 15 '23 at 21:15
It allready does change, it just isn't shown in the nework-tab. Alternatively you could try using modheader-selenium or selenium-interceptor. — kaliiiiiiiii, Mar 16 '23 at 06:59
