The guide will also explain how to install kasm behind a reverse proxy. This may also be useful for Organizr if Kasm access needs to be setup on a separate server name such as kasm.server.com.
Setting up the Kasm Tab
The Kasm tab can be setup as an Iframe in Organizr even if the test tab button returns false it may still work. Adding the URL of the Kasm is enough for the setup no other changes need to be made.
