+### Multiple Orgs
+
+Grafana does not support yet automatically provisioning the plugins with service tokens
+using `externalServiceAccounts`. More details can be found in this [GH issue](https://github.com/grafana/grafana/issues/91844).
+A workaround in this case is to turn off the feature flag `externalServiceAccounts` and
+manually create service account token for each Org. and setting it in the plugin
+configuration file. In this case, the provisioned config for the plugin will look like this:
+
+```yaml
+apps:
+  - type: mahendrapaipuri-dashboardreporter-app
+    org_id: 1
+    org_name: Main Org.
+    disabled: false
+    secureJsonData:
+      saToken: <ServiceAccountTokenForMainOrg>
+    jsonData:

+    secureJsonData:
+      saToken: <ServiceAccountTokenForTestOrg>
+    jsonData:

+
+> [!IMPORTANT]
+> It is compulsory to disable `externalServiceAccounts` feature flag in multiple Org. setting
+as plugin wont work as expected with this feature flag.
