I tried to follow this example https://docs.aws.amazon.com/dcv/latest/websdkguide/establish-connection.html and I even looked at other stack-overflow questions How to get started using NICE DCV SDK

I'm trying to run the js file using Node. I'm getting the error

/NI-SP-DCVSDK-Demo-1.0/dcvjs/dcv.js:346
     window.hasOwnProperty("webkitAudioContext") &&
     ^

ReferenceError: window is not defined
