I am creating an internal project application with the YouTube Data v3 API. Following the tutorial given in this post, I am trying to add "https://developers.google.com/oauthplayground" as a link under "Authorized redirect URIs" when editing the client_id and client_secret entry.
When I go into the console and edit the credentials, I cannot find this option anywhere. See the screenshot below to see what I see when I edit the Oauth 2.0 Client IDs.
Does anyone have an idea about why I cannot see this option or where I have to go in order to find it?
