Settting up Mesh network with Archer AX53

Hi everyone! I'm looking into setting up a mesh network with AX53 as my main router and considering buying one more device that is EasyMesh-compatible.

According to ChatGPT, I should buy another AX53 to setup the mesh network and wire it up with my current AX53 (to create Ethernet backhaul). Is this the most efficient way to do it? I'm new to this whole thing so I'm looking for some suggestion.

Thanks in advanced!
