How to properly read new group members?

Question

Python

I made a bot in the group so that it greets new people. I use telebot.
I have this code:

@bot.message_handler(content_types=["new_chat_members"])
def handler_new_member(message):
    user_name = message.from_user.first_name
    bot.send_message(message.chat.id, "Добро пожаловать, {0}!".format(user_name))

When a person enters the chat, the bot, as expected, greets him using his name ( message.from_user.first_name ). It looks something like this:

But when someone invites people, the bot greets the one who invited . It looks like this:
Question: how to make the bot write the name of the invitee in the second case , and not the inviter?

Answer 1

@bot.message_handler(content_types=["new_chat_members"])
def handler_new_member(message):
    user_name = message.new_chat_member.first_name
    bot.send_message(message.chat.id, "Добро пожаловать, {0}!".format(user_name))

Answer 2

@dp.message_handler(content_types=["new_chat_members"])
async def handler_new_member(message):
    first_name = message.new_chat_members[0].first_name
