Using Custom Authentication in an onpremise server

Hello, are there any docs about how to configure Custom Authentication for an on-premise Photon Server instance of LoadBalancing? For example, where I put the URL to use and the key-value pairs. All the docs I can find deal with how to configure it for Photon Cloud.

Thanks!

Update: Found it here, now can't figure out how to delete my post https://doc.photonengine.com/en-us/onpremise/current/reference/custom-authentication Sorry about that!
