What the panel does for a Telegram bot
Paste the token from @BotFather on the Bot page. The panel checks it with Telegram before your bot starts, then shows
the bot's @username and a link to open it in Telegram. The token is stored encrypted and handed to your code as
BOT_TOKEN and TELEGRAM_BOT_TOKEN, so most examples run without changes.
Some libraries hide a dead bot. aiogram and pyTelegramBotAPI keep retrying when the token is wrong or when the same
bot runs somewhere else, so the process stays up and nothing answers. The panel reads the console and says which one
it is: "Telegram did not accept the token", or "Another copy of this bot is running", which is Telegram's
409 Conflict error.
