The following code using python-telegram-bot (for the bot added as admin in some group) captures all kind of messages - posting messages, replies, edits. But when somebody puts like (or other emojis) on existing message, a handler function is not invoked.
from telegram import Update
from telegram.ext import Updater, MessageHandler, Filters, CallbackContext
updater = Updater(token='TOKEN', use_context=True)
dispatcher = updater.dispatcher
def handler(update: Update, context: CallbackContext):
print("here")
echo_handler = MessageHandler(Filters.all, handler)
dispatcher.add_handler(echo_handler)
updater.start_polling()
Is it possible in python-telegram-bot to get update in a handler function when somebody puts a "reaction" (like/dislike/other emojis) on message?
