Redirect URI as presented by Google gave an error.

Since "Success" was not returned in the webviewer, in OAuth2FM_GetNewAuthCodeAndToken, I had to change Set Variable [$AuthCodeFound;...]
to:
Let(
Eval = PatternCount ( $ResultSource ; "Please copy this code" ) ;

If( Eval; PatternCount ( $ResultSource; $AuthCode) )

)
