Alexa: Make sure AVS is running

I followed the steps in the demo https://matrix-io.github.io/matrix-documentation/Demos/Alexa/ but when trying to start wake word agent I get the following error:

INFO:main: Starting Wake Word Agent
INFO:WakeWordAgent: State set to IDLE(2)

Apparently I was missing to start the companion app and not to close that tab, 3 terminal windows have to be open at the same time
