The question seems to have been answered here How can I mention Telegram users without a username?, but I don't know how to write it using PTB.
The documentation link to the documentation (https://core.telegram.org/bots/api#markdown-style) also doesn't help me since I'm too much of a novice to understand it and don't know what inline or markdown is. So how should I write the code below for it to work?
context.bot.send_message(chat_id=-1111111111, text="hi")
