Lists every Google Analytics 4 property readable by the connected Google accounts of the authenticated user, and which GSC Wizard sites each property is linked to (via linkedSiteUrls). Use it to discover GA4 property IDs or to verify the Analytics setup of a site. linkedSiteUrls covers only the sites of the GSC Wizard account this connection is authenticated as (returned as account): links made from a different GSC Wizard account come back empty here even though the app shows them. An empty result with connected: false means the Google Analytics consent has not been granted in the GSC Wizard app yet (connect Google Analytics at tool.gscwizard.com first), or, with reauthRequired: true, that it was granted but Google now rejects every such account, so it has to be reconnected. errors lists every Google account whose properties could not be read (its properties are missing from the list), with the reason.
