Anybody here own the Aqara H2 Switch(US)? Is the extra button exposed over Matter?

[u/Rice_Eater483]

I have a good use case for the H2 Switch in one of my bedrooms. But they don't guarantee the extra button is available on all platforms. I watched some videos and this one Youtuber did connect it to ZHA(which I use) but didn't have access to the extra button. He then connected it over Matter and did have access to it, but it was the Matter Bridge method using an Aqara hub.

I have a SLZB-07 which I flashed to use as a Thread Border Router so I would prefer to use that. Considering the extra button is exposed using the Matter bridge method, does that mean it should definitely be there when connected directly to HA using Matter over Thread? I hope someone who has it could just tell me. But I figure that logically that should be the case right?
