Error POST API Pluggin Button

Hi everyone,
I have installed the plugin https://grafana.com/grafana/plugins/cloudspout-button-panel but when performing the POST action it gives me the error: has been blocked by CORS policy: Response to preflight request doesn’t pass access control check : No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.


Can it be solved in any way?

Thank you.
