In Gravio Studio for Windows, press the Open Browser button in the same way to obtain the token, but an error screen will appear. In this state, copy the URL from the address bar and press the Get button with that URL as the pace in the panel. Press the Set button to automatically set the token to the OAuth2 access token property.

Pressing the Open Browser button will automatically authenticate the user in the browser. If necessary, please follow the on-screen instructions for the login process, etc.

When the authentication is completed, an error message “This page is unreachable” will be displayed.

Paste the copied URL into the panel and press the Get button, and the OAuth2 access token will be “obtained”. Press the Set button to close the panel.
