Not working with current WP 6.3.1

Great idea! I downloaded the plugin – my slightly dyslexic brain read “Compatible up to WordPress 6.1.3” as 6.3.1, so I thought I was good to go. Spent some time creating a fabulous new Client Dashboard page for my client, but it’s not showing up. Not sure what to do as it seems the author hasn’t maintaining the plugin for WP updates. I hope this isn’t the case, because I really like the idea very much as a client site handover tool, and would use it for all my clients’ sites that I develop.
