I have the following code:

def message_handler(update: Update, context: CallbackContext):    user = update.effective_user
    chat_id = update.effective_chat.id    chat_type = update.effective_chat.type
    # Check if the message is sent in a supergroup and not from a bot or an administrator
    if chat_type == 'supergroup' and user and not user.is_bot and not user.id in [admin.user.id for admin in context.bot.get_chat_administrators(chat_id)]:        # Load settings
        settings = load_settings()
        # Check if flood control is enabled        if str(chat_id) in settings and settings[str(chat_id)].get('flood') == 'on':
            # Check for flood            current_time = time.time()
            if user.id not in context.chat_data:                context.chat_data[user.id] = {'last_message_time': current_time, 'message_count': 1}
            else:                user_data = context.chat_data[user.id]
                if current_time - user_data['last_message_time'] <= FLOOD_PERIOD:                    user_data['message_count'] += 1
                else:                    user_data['message_count'] = 1
                user_data['last_message_time'] = current_time
            # If flood detected            if context.chat_data[user.id]['message_count'] >= FLOOD_THRESHOLD:
                # Delete the flood messages                context.bot.delete_message(chat_id=chat_id, message_id=update.message.message_id)
                # Check if user has already been warned
                if not context.chat_data[user.id].get('warned', False):                    # Send warning message
                    warning_message = f"⚠️ Warning: User {user.mention_html()} has sent {FLOOD_THRESHOLD} or more messages in {FLOOD_PERIOD} second(s). Further spamming will result in a mute."                    context.bot.send_message(chat_id=chat_id, text=warning_message, parse_mode='HTML')
                    context.chat_data[user.id]['warned'] = True                else:
                    # Mute the user for 1 hour                    permissions = ChatPermissions(can_send_messages=False)
                    try:                        context.bot.restrict_chat_member(chat_id=chat_id, user_id=user.id, permissions=permissions, until_date=current_time + 3600)
                        # Send notification about the mute                        mute_notification = f"???? User {user.mention_html()} has been muted for 1 hour due to continued spamming behavior."
                        context.bot.send_message(chat_id=chat_id, text=mute_notification, parse_mode='HTML')                        # Reset user's message count and warned status
                        context.chat_data[user.id]['message_count'] = 0                        context.chat_data[user.id]['warned'] = False
                    except Exception as e:                        print(f"Error while muting user: {e}")

The bot is supposed to delete all of the user’s spam messages, but for some reason it deletes only the last message before the warning message, not all spam messages.

I want the bot to delete all of the user’s spam messages. Apparently, according to this code, there is a problem with the condition or I don’t know what the problem is.
