How to get the cluster ID to setup nginx proxy for iframe authentication

I'm trying to set up an Nginx proxy to log in so that my iframes are already logged in. I'm not sure how to get access to cluster ID

I think you need to provide Cluster-ID only if you run Kibana on Cloud. Do you run Kibana on-premise or on Cloud? There is an example of setup Auto-authenticating to iframe-embedded Kibana dashboard

Thank you for getting back to me. I am running the Kibana on Cloud when I looked at that article I need to provide a Cluster ID that I cant find or unsure where it is stored

@seppar The Kibana id is the first path in the Kibana URL that the Cloud console provides you, eg from https://cloud.elastic.co/deployments/9b1....d7a/kibana (where 9b1... is the deployment id), click the "Copy Endpoint URL", which will give something like https://21d....23c.us-east-1.aws.found.io:9243

21d....23c is the Kibana id to use
