Aqara M200 plus SkyConnect inside of one Thread network

Hi,
I added a SkyConnect for Matter when I created my Home Assistant Network. Now I added a Aqara M200 and now realize that it has an own Thread network which I really don’t like. I would like to have just one network and I’m even not sure if I will keep the M200. Unfortunately, now it kind of graps all new devices and adds it to its own network.
So I’d like to move it to my Home Assistant Thread network. How can I do that? I tried to generate a QR code from the Aqara App and add it as a new device to HA but that ends up with an error… Any idea what I can do?
Thanks,
Thomas
