Im using this code

import os
import pickle
import google.oauth2.credentials
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

CLIENT_SECRETS_FILE = "client_secret.json" # for more information  to create your credentials json please visit https://python.gotrained.com/youtube-api-extracting-comments/
SCOPES = ['https://www.googleapis.com/auth/youtube.force-ssl']
API_SERVICE_NAME = 'youtube'
API_VERSION = 'v3'

def get_authenticated_service():
    credentials = None
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            credentials = pickle.load(token)
    #  Check if the credentials are invalid or do not exist
    if not credentials or not credentials.valid:
        # Check if the credentials have expired
        if credentials and credentials.expired and credentials.refresh_token:
            credentials.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                CLIENT_SECRETS_FILE, SCOPES)
            credentials = flow.run_console()

        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(credentials, token)

    return build(API_SERVICE_NAME, API_VERSION, credentials = credentials)

def get_video_comments(service, **kwargs):
    comments = []
    results = service.commentThreads().list(**kwargs).execute()
    while results:
        for item in results['items']:
            comment = item['snippet']['topLevelComment']['snippet']['textDisplay']
            comments.append(comment)
        # Check if another page exists
        if 'nextPageToken' in results:
            kwargs['pageToken'] = results['nextPageToken']
            results = service.commentThreads().list(**kwargs).execute()
        else:
            break

    return comments


if __name__ == '__main__':
    # When running locally, disable OAuthlib's HTTPs verification. When
    # running in production *do not* leave this option enabled.
    os.environ['OAUTHLIB_INSECURE_TRANSPORT'] = '1'
    service = get_authenticated_service()
    videoId = input('Enter Video id : ') # video id here (the video id of https://www.youtube.com/watch?v=vedLpKXzZqE -> is vedLpKXzZqE)
    comments = get_video_comments(service, part='snippet', videoId=videoId, textFormat='plainText')

print(len(comments),comments)

good luck
