Slack records a device id when you log in -- have you noticed that you get a notification saying that you've logged in from that device? And a lawyer won't care that it's your personal device. They'll want to see it because it shows up in an audit log from your employer. They'll want to check: have you saved any work content? Have you copy/pasted work messages elsewhere? Just about anything is fair game once the device is identified.
