[Python] Chat not found - Telegram bot

I created a Telegram bot using @BotFather, and it works correctly with my own chat_id. However, when I use a different chat_id, it raises the following error:

API Response: {"ok":false,"error_code":400,"description":"Bad Request: chat not found"}


Do I need to add permissions, or how does it work?

This is my code for sending the message:

"""Telegram utilities."""

# Django
from django.conf import settings

# Utilities
import requests


def send_telegram_message(chat_id, message, parse_mode=None):
"""Send a message to a Telegram chat."""

token = settings.TELEGRAM_TOKEN
url = f"https://api.telegram.org/bot{token}/sendMessage?parse_mode=HTML"
data = {"chat_id": chat_id, "text": message}
if parse_mode:
data['parse_mode'] = parse_mode
try:
response = requests.post(url, data=data)
response.raise_for_status()
except requests.exceptions.RequestException as e:
print(f"Error al enviar mensaje de Telegram: {e}")
if e.response is not None:
print(f"Respuesta de la API: {e.response.text}")
