I built a telegram bot with python-telegram-bot and I created a webhook with flask.

I tried deploying to ubuntu and running the server with gunicorn. However, I think both the telegram bot and flask app needs to be started but I cant seem to get this to work. I have only succeeded in running either of the two.

This is my code.

from flask import Flask, Blueprint
import logging
from telegram.ext import ApplicationBuilder, CommandHandler, Application, ContextTypes
from config.configuration import Config as CG
from bot.trivial_operations import start, unknown_handler, echo, logger
from bot.pdf_operations import conv_handler_file
from flask import Blueprint, request
from telegram import Update, Bot


telegram_token = CG.telegram_api_key


def create_app():
    app = Flask(__name__)
    app.config.from_object(CG)
    # app.register_blueprint(webhook_bp)

    application = (
        Application.builder().token(telegram_token).updater(None).build()
    )

    @app.route("/webhook", methods=["POST"])
    async def webhook():
        logger.info("Received webhook")
        logger.info(request.get_json(force=True))
        # await application.process_update(Update.de_json(data=request.get_json(force=True), bot=bot))
        await application.update_queue.put(
            Update.de_json(data=request.get_json(force=True), bot=application.bot)
        )
        return 'ok'

    application.add_handler(CommandHandler('echo', echo))
    application.add_handler(CommandHandler('start', start))

    application.add_handler(conv_handler_file)
    application.add_handler(unknown_handler)

    return app, application


async def main():
    app_, bot = create_app()
    await bot.initialize()
    await bot.start()
    logger.info("Flask not")
    app_.run(host="127.0.0.1", port=5002)
    logger.info("Flask running")
    await bot.stop()
    await bot.shutdown()

my wsgi.py file

import asyncio

from config.app import main, create_app

app = create_app()[0]

if __name__ == "__main__":
    asyncio.run(main())

and my gunicorn service
