Arduino Matter thread board adding to Homey

I recently bought a silicon dev20270 board which I hoped I could connect to my homey pro using Matter. After uploading the first code on the board and trying to connect the board I got a message the device cannot be added because it is not certified. Does someone know a way to add uncertified devices(which I made myself) so I can play around with it. I know there are apps which allow you adding your Arduino boards using wifi but would like to use Matter if possible. Also not sure if you could maybe add those devices if you would make a app?

So if someone has any idea if and how it’s possible let me know. Thanks
