Bungie.net Destiny API error

[FireFighter1017]

When I try to connect to Bungie's API with my developers API key, it fails with this error:
Error: Get "https://www.bungie.net/Platform/Destiny2/Manifest/": oauth2: "unsupported_grant_type" "Only authorization_code or refresh_token supported."

Here's my config:

As documented and seen in the UI, only client credentials and jwt type oauth2 is supported in the plugin for now
