I can't send a comment under the post, what should I do?

Question

Python

I wrote a program that sends a comment first, but it sends the first comment only on my
group wall, under a post
in other groups with millionaires - the result is 0, and nothing is displayed, 0 errors i.e.
maybe it's in the captcha, but before dealing with the captcha, I would like to ask the opinions of the pros

import vk
import time
tok = 'token'
session = vk.Session(access_token=tok)
vk_api = vk.API(session,  v='5.92', lang='ru', timeout=10)
id_club = <id сообщества с минусом>
id_club_m = <id сообщества без минуса>
message_text = 'блин, опять не первый...'
a = vk_api.wall.get(owner_id=id_club,count=1)
x = a['items'][0]['id']
while True:
    time.sleep(1)
    if vk_api.wall.get(owner_id=id_club,count=1)['items'][0]['id'] != x:
        print('Новая запись '+'vk.com/club'+str(id_club_m)+'?w=wall'+str(id_club)+'_'+str(vk_api.wall.get(owner_id=id_club,count=1)['items'][0]['id']))
        vk_id = vk_api.wall.get(owner_id=id_club,count=1)['items'][0]['id']
        vk_api.wall.createComment(owner_id=id_club,post_id=vk_id,message=message_text)
        print('\n ------- \n работа программы завершена, запустите снова что бы оставить комментарий первым')
        break
