When developing bots, it's common practice to show typing indicator to user, while bot is working on background, but is it possible to detect opposite situation: whether USER is typing or idle? I could not find any info in docs or google. Does anybody know how to achieve that?

This currently can't be done.
You can only show the user that you are typing.
"typing_on" and "typing_off" for the sender_action.
