High-Level Summary

When a user auths with Datum Cloud they should be redirected to a useful place in the docs on how to use Datum Desktop.

Motivation

ATM if you auth with the cli you get re-directed to the docs. We should be re directing them to a more specific section of the docs for Datum Desktop.

Goals

• Once logged in via the desktop app the redirect in the browser should take you to docs on Datum Desktop.

We can do this with this code change:

@bmertens-datum do you know if there's a ticket to create docs for the desktop app? I can't see one in the MVP project.

@mattdjenkinson We do not have a docs ticket.
