Add Sonoff SNZB-01P button as a device to Alexa

Hi,
I am a new user to Homey Bridge and Homey Premium subscription. One of the main things I wanted to do is to add a physical button to activate a group of devices. I am trying to expand out of the Alexa ecosystem and thought Homey Bridge would be Ideal way of using zigbee and Z-wave products without the need of buying a hub for every brand.

I have added the Sonoff SNZB-01P button into Homey Bridge and all the 3 actions (one, two and long press) work and created 3 flows to send myself a notification for each. The problem is that after asking Alexa “Discover devices” it finds the Scenes (Flows), but not the device?
I have tried disabling and reenabling the Skill, to no avail. Any suggestions would be great.

Probably a device type “multi-function button” isn’t supported by Alexa?
