Another easy way to get auth'ed is to use a Sign in on mobile feature of the already logged in Slack workspace.

Describe the solution you'd like

In Slack, click the Workspace name, then chose "Sign in on mobile". This provides a QR code that can be used for sign-in.

You can right click the QR code and choose "Copy image URL".

The URL is a Base64 encoded string:

data:image/png;base64,iVBORw....

This makes it extremely easy to share (copy and paste) into the CLI wizard.

QR Code contains the URL in the following format:

https://app.slack.com/t/${WORKSPACE_NAME}/login/z-app-${SOME_ID}-${SOME_OTHER_NUM}-${SOME_LONG_STRING}?src=qr_code&user_id=U...&team_id=T...

Visiting this URL will do a redirect and then Slack workspace magically opens. 🎉
