Get Dashboard UID to pass from Grafana Button Panel

Is there a way to get the Grafana Dashboard UID (the same shown on the Dashboard JSON Model) to pass to an HTTP POST Request Payload that I will implement using Button Panel visualization?

Dashboard JSON Model example:

{
  ...
  "uid": "cab508cc-8055-48f1-9c16-ca22943d525e",
  ...
}

Try dashboard variable ${__dashboard.uid}

Amazing! Thanks.
