How to save data from the response of the web socket after sending a request in the UI test performed in pytest

UI test is performed in pytest (test is performed good)

'''from page_objects import MainPage, LoginPage

def test_locate_best_accept(browser):

LoginPage(browser) \
    .login_user(login='****_user', password="******")
MainPage(browser) \
    .select_symbol(symbol='ACY') \
    .select_quantity_symbol(quantity=600) \
    .select_destination_best() \
    .click_request_button() \
    .accept_request()'''

After performing the step '.click_request_button()' I need to get and save in the 'python dictionary ' data from response WebSockets. How to implement it? I am new to automated testing
