It's a lot easier to put yourself in Do Not Disturb via whatever team chat option you're using than having to hide from someone tapping your shoulder at your desk.

I wrote localslackirc :)

I basically have the ability to completely block certain people, quietly ignore channels until I get mentioned directly (@here gets ignored), and cause the abusers of @here to not generate a notification for me.

I also don't see gifs and reactions, which is a big help in not getting distracted.
