Works great but instructions are outdated

The plugin works perfectly -that’s the important part. BUT, it took me an hour to configure, which was frustrating. The instructions for oAuth connection with Google provided (won’t let me link to the instructions, but it’s the link provided from the wizard) are wrong and outdated – I did not see the same screens/order in the Google console that are shown there and had to fudge my way through.

Once I figured it out, the plugin worked flawlessly to fix our mail sending problem, but before I use this plugin on my other sites, I’d like to see the instructions updated.
Thank you!
