pyrogram - Get notified when a user joins a channel

In supergroups, my bot gets a message every time a user joins the group (by registering a MessageHandler with ~filters.private filter), so I know who it is (from the new_chat_members field) and I can kick it if it doesn't meet certain conditions (e.g. it has no username set).

However, if I put the bot in a channel, I don't get any message when a user joins it (or, at least, not by using a MessageHandler). Is it possible to get the same behavior?

Thanks

Also you can use this code:

try:
    member = await client.get_chat_member(CHANNEL_ID, chat_id)

    if member.status not in [ChatMemberStatus.MEMBER,ChatMemberStatus.OWNER,ChatMemberStatus.ADMINISTRATOR]:
        raise Exception("Not a member")
except:
    keyboard = InlineKeyboardMarkup(
        [[InlineKeyboardButton("Join in ChannelšŸ“¢", url=CHANNEL_LINK)]]
    )
    await message.reply_text(
        "You must join in channel to use the bot",
        reply_markup=keyboard
    )
    return

In Groups and Supergroups this works by Telegram sending a Service Message, which you receive via filters.new_chat_members, or in groups >= 10 000 members via a ChatMemberUpdated event (ie no new Message).

Channels do not have such an update, and thus you cannot handle anything like this. Your best bet is to periodically query the Recent Actions by using app.get_chat_event_log(), and filter for the returned list for the events you want.
