You screenshot doesn't show how you achieved this or that you're even using Linux. There is no option to start a secret chat for me on a right click. Where did you download your client?

This ticket suggests that there's no such option: https://github.com/telegramdesktop/tdesktop/issues/871

Those are the same link and they’re 10 years old.

I am using telegram-desktop from aur, I clicked the three dots (…) at the top next to the magnifying glass, then info (i) to get to the profile, then there is a “more” (…) button where there was a “Secret” option.

Thanks, this looks interesting. However, it seems unofficial. There's no such option in the official client from telegram.org.

Thanks, I fixed that.

I’m not aware if it’s official or not, but to be clear, I like that telegram allows open source and alternative clients.
