How to mark part of a text as quoted in Telegram sendMessage Bot API?

Recently Telegram has provided the ability to quote texts:

I want to send a message using Telegram Bot API using html as parse_mode but I cannot find any mention of how to do it using html tags in official docs.

How is this achievable?

If you want to quote a specific part of a message (for it to appear as a clickable object).
You can modify reply_parameters in method sendMessage.

I didn't manage to build a post request that sends message with such quote, but here is how it looks using Aiogram3:

from config import TOKEN, chat_id, message_id
from aiogram import Bot, types
import asyncio

bot = Bot(token = TOKEN)

asyncio.run(
    bot.send_message(
        chat_id=chat_id,
        text='Quoting the message!',
        reply_parameters=types.ReplyParameters(
            chat_id=chat_id,
            message_id=message_id,
            quote='this'
        )
    )
)

Unfortunatelly, I can't post screenshot to show how it works...
That's my first ever stackoverflow answer 😅

You can also simply format message like as if it has a quote.

If you desire to use HTML formatting, there is a <blockquote> tag.

This is not a quote
<blockquote>But this is!</blockquote>

Or you can set parse_mode to MarkdownV2 and use the format below:

This is not a quote
> But this is!

That's how it looks with Aiogram3:

from config import TOKEN, chat_id, message_id
from aiogram import Bot, types
import asyncio

bot = Bot(token = TOKEN)

asyncio.run(
    bot.send_message(
        chat_id=chat_id,
        text=(
            'This is not a quote\n'
            '<blockquote>But this is!</blockquote>'
        ),
        parse_mode='HTML'   
    )
)
