How to combine bot and channel functions in one telegram bot in aiogram?

Question

Telegram

Good afternoon.
New to python and telegram-bots. The task is to combine the functions of the bot and the channel in one bot\channel. Namely, so that the administrator of the bot \ channel has the ability to create publications that all users will see, while the bot responds to user commands.
The bot is ready and working on aiogram, responds to commands, tried to add it to the channel, but on the channel does not respond to commands. I don't know what to do, a google search turned up no results.
I don't attach the code, because there is nothing special in it, simple handlers "@dp.message_handler(commands=['start'])".

Answer 1

Found a solution. You need to create a database for the bot, where user data will be written after the /start command. Through the admin panel or the command to create a post, sending it via "await bot.send_message/send_photo" to users registered in the database.

Answer 2

Publications in the channel should be caught not by message_handler, but by channel_post_handler.

@dp.message_hander()
def process_message(message):
...

@dp.channel_post_handler()
def process_post(post):
...
