Add Insteon scene (group) 'button' to HomeKit?

I have an Insteon scene that I trigger via a service call:

type: button
  action: call-service
  service: insteon.scene_on
    group: 1
  target: {}
name: Downstairs On
icon: mdi:weather-sunset-up

And I want to be able to run that scene from HomeKit. With my previous home bridge integration I created a virtual switch (where I reset it to ‘off’ after the scene was set). How can I set that up in Home Assistant?
