How exactly do I set up the expandable part in my MySQL DB?

[qas]

I added the 'Expandable' plugin (https://github.com/zeroasterisk/CakePHP-Expandable-Plugin) to my plugins folder. It now is trying to check my 'default' DB to see if 'opauth_settings' and 'opauth_settings_expandeds' exists as individual MySQL tables. What am I to add into these tables specifically?

I currently have these tables set up (listed below) in my default DB and it's returning "False" for
$data = $this->GoogleDriveFiles->listItems();
debug($data);

TABLE NAME (COLUMNS)
opauth_settings (id, name)
opauth_settings_expandeds (id, opauth_setting_id, key, value)

I am eager to get the Google APIs working. Opauth is configured correctly but once I get through this, I'll be on my way to working with the APIs. Looking forward to any help on this.
