     * We could make this more interactive:
     * - Get status ('yarn bw status') and parse it
     * - Set server url automatically if its not set. Fail with error if it is set but different
     * - Prompt for username & password if not logged in. Login and store session id in memory
     * - Prompt for password if locked. Unlock and store session id in memory
     * - Session id can then be passed to `sync` & `list items` commands with --session
     * Reasons to not do this:
     * - The script becomes more complex
     * - Additional security concern of handling password entry
     * - Password would need to be entered every time the script is run (rather than just once per terminal session)
     * - Blocker: unlocked status is not reported correctly: https://github.com/bitwarden/clients/issues/2729. This
     *   makes it really hard to determine the correct course of action.
