Alexa.PowerController. Toggle light rather than just turn on

I have a shelly connected up and works great with Alexa (haaska) if I say “Alexa, turn on study light”, or “Alexa, turn off study light”.

When I say just “Alexa, Study Light” the command that is sent to HA is “Amazon Alexa sent command Alexa.PowerController/TurnOn for Study Light”. This means that it only turns the light on, and won’t turn off the light.

I know I could change this in Alexa dev tools, but I want to keep the config in HA. Is there a way to make the command to light.toggle rather than just turn on.
Thanks!
