Telethon Delete from contacts by phone number, how?

Question

Python

Hello.
There is a list of phone numbers that need to be removed from contacts via Telethon . I
use this code for this:

def delete_contact():
    with open('phone.txt', 'rt') as f:
        phone_list = f.read().split('\n')
    with TelegramClient(name, api_id, api_hash) as client:
        result = client(functions.contacts.DeleteByPhonesRequest(
            phones=phone_list
        ))
        print(result)

The code returns True as it should, but the numbers are not removed from the contacts.
Who will tell you how to fix it?

(passed a sheet with numbers, and each number separately, does not work)
