Posthog is not available on Drupal.org

I understand that it is a work in progress but would like to help test

Thanks, I added posthog 1.x-dev for you. But you'll have to wait some more weeks to get to a really useful point here :)

See https://www.drupal.org/project/posthog/releases/1.x-dev →

Automatically closed - issue fixed for 2 weeks with no activity.
