How do I reset Google #Sitekit in #wordpress, completely?

I've logged into Google Search Console and removed all properties.

I've uninstalled the #wordpressplugin for Google SiteKit and re-installed.

I get Screenshot#1: saying "SiteKit is already setup".

When following the prompt to login to the google account, I get Screenshot#2 saying permissions already exist.

When I click continue: I get an authentication error.

Do I need to clean my #WordpressDatabase?

How do I resolve this issue?
