How to detect Telegram Chat IDs

... by opening https://web.telegram.org/ in a Browser:

for a user

group

Open the group's chat window and inspect the URL: https://web.telegram.org/#/im?p=g[GROUP_ID] ⇒ the chat ID will be -[GROUP_ID] (prepend a minus)

public channel

The chat ID is an @ sign, followed by the channel's name.

private channel or supergroup

Open the channel's chat window and inspect the URL: https://web.telegram.org/#/im?p=c[SOME_DIGITS]_[EVEN_MORE_DIGITS] ⇒ the chat ID will be -100[SOME_DIGITS] (prepend a minus and 100, leave out the underscore and following numbers. The ID is always a 13 characters negative integer).
