Attempting to login using Oauth Implicit Grant, using docs: https://developers.digitalocean.com/documentation/oauth/

Sample auth request:

https://cloud.digitalocean.com/v1/oauth/authorize?scope=read&client_id=123&state=k3uWpyJb&redirect_uri=https://789.ngrok.io/auth&response_type=token

After entering credentials, the URL received at the callback contains no parameters.

Expected behaviour: should have a token parameter.
