Kernel Version: 6.4.12-arch1-1 (64-bit)

ADDITIONAL INFORMATION
Telegram is running from Flatpak. I don't know of its inner working, but maybe
it containerized PID namespace just like docker? From the outside, app's PID is
4-digits which is pretty much what you would expect from a normal user process.
