ADD ON SATELLITES COMPATIBLE WITH My Current SXK30 setup?

[BJ24]

Need to add 1 more satellite to cover a large room above the garage. I have the NETGEAR Orbi Pro WiFi 6 Mini Mesh System (SXK30) | Router with 1 Satellite Extender for Business or Home | VLAN, QoS | Coverage up to 4,000 sq. ft., 40 Devices | AX1800 802.11 AX (up to 1.8Gbps)

You can get used/renewed SXK30 systems for cheaper than you can buy a satellite by itself. Might be worth getting it for satellite and having a backup router.
