I am struggling with configuring the authentication properly since the Authentication button doesn't work.
I have enabled the google calendar API on my account.
Tried creating both an API key as well as creating a OAuth 2.0 Client IDs with the settings that home assistant requires. I was unable to get either to work and still get the "Not authenticated or invalid authentication" banner.
I am unsure of what to set as the key name in the custom parameters. Potentially this is all I am missing or messing up. All the posts I can find talk about the calendar settings, but brush over the authentication settings.
Hopefully I am just missing something silly, but any help is appreciated. Thanks!
