Slightly off topic but what proton subscription do you have? Proton Unlimited is email + storage via Drive with 500GB and VPN for $12.99/mo if paying monthly, otherwise it’s $10/mo or $8/mo if you pay 1 or 2 years in advance, respectively.

Same, just used it today in fact.

There’s another one on GitHub that uses the command line, but lasim is easier to use and faster.
