If you have it connected to a hue hub, I believe it can come in through the matter integration if you want to use that method. But then you lose some of the other features you normally have for the lights. 
Otherwise, there is a community-created edge Driver which can bring in the button if it is connected to a hue bridge without losing any functionality, but the setup is a little complicated. You can read about that in the following thread.
[ST Edge] Philips Hue LAN [BETA] (3rd Party Driver, Not ST Native)
Several people have posted about attempts to get a hue button to work without a connection to the hue bridge, but so far I haven’t seen anyone be successful in that approach. 
hopefully if someone does have it working, they will post.
