Reality Capture installed on local server/desktop/virtual machine and used through API

Hello,

I am trying to use Reality Capture installed on desktop, through API. My goal is to create WebApp which will allow a user to upload photos and receive report from analyse set like in CLI script.

The problem I have is that I cannot find any information how to aquire clientID, appToken and Session required by API methods.

Data used in sample JS app on screenshot below are just random strings.
