If you run
snap info [snap name] --verbose, you can see how the snap is confined.
But I tend to use
snap info mailspring --verbose | grep confinement as it is quite a lot of output at times.
❯ snap info mailspring --verbose | grep confinement
Standard Verbose Output
❯ snap info mailspring --verbose

If your work revolves around email, Mailspring Pro adds even more features,
supercharging the app with read receipts, link tracking, send later,
reminders, contact profiles, email analytics and more. At $8/mo, Mailspring

In order to use Mailspring, you need to create a Mailspring account.

cloud. Your Mailspring ID holds things like snooze dates and mail rules, so
you can re-install Mailspring or use it on two computers at once.
