Security recommendations
Use least privilege for the service account and token, scope it to the project, set short expiration, and rotate regularly.

Share to Slack

Capture dashboards with the Renderer and attach them to Slack as files.

Use a CronJob or scheduler to generate dashboard images at the required times and share them with your team.
