Solved the issue. I had wondered why I couldn’t see the option for “Plugin Publisher” when creating a new API key, apparently there are two separate API key sections of Grafana Cloud… So, to anyone else who runs into this, ensure you use the link at the top of the cloud home app here:
And then you will see the option for the plugin publisher role as shown below.
Do not use the API Keys under the configuration gear icon in the left menu…
