In VMware vSphere Client, there is a button on each VM labelled "Launch Remote Console", which should open in an external app (VMware Remote Console). This doesn't work in Orion - it's fine in Safari/Chrome/etc. No response is received when pressing the button. I have tried disabling Content Blockers etc, and using Compatibility Mode to no effect.
