I setup the local Hello World sample with the rig, followed all the setup instructions and things generally seem to work. But when I click on the button in the example or try any of the sample messages nothing happens. If I put a call to log to the extension log in the head section of the sample page that seems to work, but no other javascript events are firing. I’m on widows and using chrome. ---

How did you start the Dev Rig: “yarn start”, “run.cmd”? ---

Which environment variables? The documentation said to run a setup script, there was nothing about environment variables. ---

Well, got the beta version and it seems to be working better. But not seeing a button for the sample messages. ---
