Matter device: LAN controlled and reversed state

A Matter device (Wiz GU10 bulb) connected to NSPanel Pro is shown in the application as LAN available. Since it is not, what does LAN availability really mean for Matter devices?
Why is it not possible to configure a button (remote) so that a click reverses the status of the Matter bulb? Just like it happens with Zigbee bulbs or switches. Is this an oversight in eWeLink or a limitation of the Matter platform?

I have added MINIR4M to Nspanel pro as a matter device. I can control MINIR4M using the R5 remote control thanks to the scene set in the eWeLink application.
