Google Ads Api Oauth Catchable Exception

```php
try {
// Generate a refreshable OAuth2 credential for authentication.
$oAuth2Credential = (new OAuth2TokenBuilder())
->withClientId(env('GOOGLE_ADS_CLIENT_ID'))
->withClientSecret(env('GOOGLE_ADS_CLIENT_SECRET'))
->withRefreshToken($refreshToken)
->build();
} catch (\Throwable $e) {
return $this->job->fail();
}

try {
// Construct a Google Ads client configured from a properties file and the
// OAuth2 credentials above.
$googleAdsClient = (new GoogleAdsClientBuilder())
->withOAuth2Credential($oAuth2Credential)
->withDeveloperToken(env('GOOGLE_ADS_DEVELOPER_TOKEN'))
->withLoginCustomerId($customerID)
->withTransport('rest')
->build();
} catch (\Throwable $e) {
return $this->job->fail();
}
```

So i have the code above which is using the google auth library to create the oauth credential, however some of our clients have expired refresh tokens: This spits out:

```

Client error: POST https://oauth2.googleapis.com/token resulted in a 400 Bad Request response:

"error": "invalid_grant",
"error_description": "Token has been expired or revoked."

```

Is there a good way to be able to catch that since it's being caught inside the libraries and i'm not seeing a way to properly handle that exception.
