Ikea shortcut buttons via homekit / bridge

Hello

New to HA. My setup is some ikea outlets and lamps connected to ikea bridge and a Meross outlet via a homebridge raspberry pi installation. Home assistant runs on another pi zero. Everything works flawless but my ikea short cut buttons a only programmable in the ikea app. I see the different actions in the apple home app but I do not have a HomeKit hub as I use already home assistant. But in ha the buttons have no states other than the battery level. Am I missing anything here?
In HA I use the ikea integration and also a HomeKit bridge via homebridge.

Thank you for your help as I would like to attribute a light toggle and other conditions which Ikea does not offer.
