Telegram – Read messages from specific forum (group) topic using telethon v1

I am working on a project and I would like to fetch first 10 messages from a specific group topic in telegram, unfortunately I can’t find any way for this in documentation.
I am using telethon 1.30.3.

I’ve tried to use standard TelegramClient.get_enitty for this with a direct link to forum topic channel = await client.get_entity('https://t.me/ddostup/1118'), but telethon failed to work with it.

    The solution lays in internal implementation of topics by telegram. Topics are implemented as message threads, so all messages in group(forum) topic have reply_id being set to topic id

    Thus this code will iterate over all messages in a group topic

    async for message in client.iter_messages(channel, reply_to=topic_id, limit=10)

    simply to do it you can follow up my code :
    Make sure you create a APP in the dev section and repalce the app_id as well api_hash

    from telethon import TelegramClient, events
from loguru import logger


# Replace YOUR_API_ID and YOUR_API_HASH with the values from your Telegram API
api_id = ''
api_hash = ''
channelsNames = ["prdscloud"]
client = TelegramClient('session_name', api_id, api_hash)

async def main():
    await client.start()
    for channel_username in channelsNames:
        try:
            logger.info("Checking for logs in channel: 🔥🔥 " + channel_username)
            messages = await client.get_messages(channel_username, limit=10, offset_id=0)
            if not messages:
                break
            logger.info("Found " + str(len(messages)) + " messages.")
        except Exception as e:
            print(e)
            pass
    print("All messages have been fetched.")

client.loop.run_until_complete(main())
