This actually came up with multiple companies I worked at in Sweden. Apparently the law here is quite strict that you _can_ use your computer for personal matters and that your employer is not allowed to spy on you on those matters.
So they can monitor your email and slack server-side, but not your client-side stuff that doesn't touch their servers. However if you use a VPN then they can also monitor your DNS requests and every website you visit. Any kind of client-side telemetry is limited to a few things, however those things can involve what applications you have installed (like spotify) for security reasons or USB sticks plugged in.
