> it gets a bit tricky when you ask urgent question to colleague and he is not responding to you for 30 minutes.
This type of interruption culture is very harmful both directly to productivity (it takes a long time to get back to focus from being interrupted) and also to mental health from the pressure of being constantly interruped and expected to jump at every slack message.
There should be no question that is so urgent that it can't be answered tomorrow. Do a full day of work and check & answer your messages once a day, morning or evening.
The exception is people on call who of course do need to respond to things within minutes but that's why being on call is so exceptionally stressful. Rotate that so nobody is subject to such stress very often.
