Question about Netgear RBK352 Orbi WiFi 6 Dual Band Set of 2

Dear Community I would like to set up a new WLAN after my old AP died (thank you, Digitec for the uncomplicated return). Since my flat cannot be covered with one AP, I wanted to buy a MESH system. But since I have LAN cabling everywhere, it would make sense to wire the APs via LAN. However, it is not clear to me whether I can connect the APs directly to the LAN (where the modem is already connected) or whether the router and satellite can only be connected via a dedicated cable. Further, if you don't do that, would it be possible to attach wired devices to the ports (specific to MK62)? Thank you very much. LG
