What code does TelegramClient use to send stickers to groups?

I am making a software for telegram, which will send a certain number of messages in the form of stickers through the telegram chat database, after the end of the cycle wait 24 hours and repeat the cycle. but the code itself does not work for some reason.

Here is the code itself:

from telethon.sync import TelegramClient
import time
import datetime

API_ID = 25133720  
API_HASH = '08af2f4d9e4c65cb242d220e533338e8'

messages_sent = 0

def main():
global messages_sent

chat_usernames = ['@forexjobinkiev', '@spb_work_choogl', '@temshchik_chat', '@work_online_today',     '@freelancerchat1', '@chat_sportbetwiner', '@SravkiS', '@dropshiping_tovarka_ua', '@Kiev_Work_Job682',     '@robota_com5']

with TelegramClient('anon', API_ID, API_HASH) as client:
    while True:
        current_time = datetime.datetime.now().time()

        if current_time.hour == 0 and current_time.minute == 0:
            messages_sent = 0

        if messages_sent < 35:
            for chat_username in chat_usernames:
                chat_entity = client.get_entity(chat_username)
                for sticker_id in   ['CAACAgEAAxkBAAK2RmTUSWd8kMnKSh4vNz_YpKaRGL2tAAIuAwAC4WihRo38v4W03s7TMAQ', 'CAACAgEAAxkBAAK2SGTUSYInvjbUPyaP3mpG22JsVhjiAAIYBAACwHKgRlJDWLOjrJKVMAQ']:
                    client.send_sticker(chat_entity, sticker=sticker_id)
                    messages_sent += 1   
                    if messages_sent >= 35:
                        break
                    time.sleep(20)

        next_day = datetime.datetime.now() + datetime.timedelta(days=1)
        time_to_wait = datetime.datetime.combine(next_day.date(), datetime.time.min) -     datetime.datetime.now()
        time.sleep(time_to_wait.total_seconds())

if __name__ == "__main__":
main()

It does not detect any errors by default except PIP, but after running the code it shows the following:

Traceback (most recent call last):
    File "C:\Users\User\PycharmProjects\pythonProject4\main.py", line 37, in <module>
    main()
    File "C:\Users\User\PycharmProjects\pythonProject4\main.py", line 26, in main
    client.send_sticker(chat_entity, sticker=sticker_id)
    ^^^^^^^^^^^^^^^^^^^

    AttributeError: 'TelegramClient' object has no attribute 'send_sticker'
