Issue with Capturing New Members in aiogram Bot when "Hide Members" is Enabled

I'm working on creating a welcome bot using the aiogram library to greet new members who join a group. However, I'm encountering an issue when the group has enabled the "Hide Members" setting. In this case, new members joining the group don't receive the standard "user joined the group" notification. As a result, the @dp.message_handler(content_types=types.ContentTypes.NEW_CHAT_MEMBERS) method doesn't seem to capture these new members.

Has anyone else faced a similar issue? If so, how did you manage to handle the situation? Is there a way to detect new members joining a group even when the "Hide Members" setting is active?

I would greatly appreciate any insights or suggestions on how to overcome this challenge. Thank you in advance for your help!

Best regards,

When starting the Bot, include "chat_member" in allowed_updates, and then use app.add_handler(ChatMemberHandler(callback, chat_member_types=0)), and it will work.

Code demo (using python-telegram-bot):

from telegram import Update
from telegram.constants import ChatMemberStatus
from telegram.ext import Application, ChatMemberHandler, ContextTypes


async def member_status_change(update: Update, context: ContextTypes.DEFAULT_TYPE) -> None:
    """
    Handle chat member status changes.
    """
    assert update.chat_member
    chat = update.chat_member.chat
    user = update.chat_member.from_user
    old_status = update.chat_member.old_chat_member.status
    new_status = update.chat_member.new_chat_member.status

    # Log the status change
    print(f"[Chat ID: {chat.id}] {chat.title or 'Chat'}: User {user.full_name} ({user.id}) status changed "
          f"from {old_status} to {new_status}")

    # Example: Implement specific actions based on the status change
    if old_status == ChatMemberStatus.LEFT and new_status == ChatMemberStatus.MEMBER:
        print(f"User {user.full_name} has joined the chat.")
    elif new_status == ChatMemberStatus.BANNED:
        print(f"User {user.full_name} has been banned from the chat.")


def main():
    """
    Start the bot.
    """
    # Replace 'your-bot-token' with your actual bot token.
    bot_token = 'your-bot-token'

    # Create the application
    app = Application.builder().token(bot_token).build()

    # Add ChatMemberHandler to monitor and handle chat member status changes
    # chat_member_types=0 means that the handler will only handle chat_member updates
    app.add_handler(ChatMemberHandler(member_status_change, chat_member_types=0))

    # Run the bot with explicit allowed_updates (limiting it to 'chat_member' updates)
    # Remember to add other allowed_updates if you need them
    print("Bot is running...")
    app.run_polling(allowed_updates=['chat_member'])


if __name__ == '__main__':
    main()
