How to download message as bot?

[pocomane]

I used ./tg init --token my-bot-token. Then I tryied to ./tg download chatid msgid and got

tg: callback: not authorized: run `tg login` first

while ./tg download --bot chatid msgid says:

tg: unknown flag: --bot

If I do ./tg login first, the download command (without --bot), gives:

tg: callback: resolve peer "XXXX": contact not found

I assume this is because it is trying to dowload it as the logged user, not the bot.

It seems to work. It makes sense?
