How to collect several information and send it at the right time?

Question

Python

LongPoll VKontakte returns various events, and one of them in object.action is chat_invite_user, which fires every time a new participant is invited to the conversation.
And this event is checked in my code and every time a new participant is invited, my bot greets him: "Welcome you First Name Last Name!", but there is such a function in VK where you can invite several participants at once and for example if the conversation administrator invites 10 participants, the bot greets everyone with a separate message, which is extremely inconvenient and not beautiful, I would like to implement something like this: "Greetings to you First Name Last Name, First Name Last Name, First Name Last Name ...", but I can't imagine how to do it, because longpoll sends a separate event for each.
The code:

from vkbottle import Bot, Message
from vkbottle.rule import ChatActionRule
from modules import get_name, settings

bot = Bot(tokens=settings.TOKEN, group_id=settings.GROUP_ID)

@bot.on.chat_message(ChatActionRule(["chat_invite_user"]))
async def invite(ans: Message):
  first_name, last_name, id = get_name(ans.action.member_id)
  await ans(f"Приветствуем вас @id{id} ({first_name} {last_name})")

bot.run_polling(skip_updates=False)
