Question

macOS

Telegram is installed on the poppy, there is an icon in the top panel, that's enough for me.

How to remove it from the dock?

Answer 1

In general, there is no simple solution. especially on extreme versions of the system.
There are workrounds of varying degrees of badness, but it’s easier to storm developers to add such functionality to applications (by the way, there is such a rikquest for the cart, and more than one).
specifically for the cart, this is solved by the command

sudo /usr/libexec/PlistBuddy -c "add :LSUIElement bool true" /Applications/Telegram.app/Contents/Info.plist

and re-signing the application.
from the bad: you need to repeat after each update, and the application will not be visible with opt+tab .
