:( Those aren't great either... Mine uses... everything. Our scrum master put us on teams, yet she's herself still chatting using Skype. I use Teams with the two co-workers I work together with the most, and there's managers @-ing everyone in there too. There's 3 extra whatsapp groups (all muted, because they aren't serious business only)...
Today I quit all of it and had a lovely 5 hours of productivity.
