How to set up Tenda Nova mesh for wired backhaul - MW5, MW6, etc.

I'm testing again both units individually today (with only one node powered on and connected to WAN). The problem still persists. Moreover, I was able to install several old versions of Tenda WiFi (3.x.x series) but Bridge mode does not exist in the setup wizard.

I observed that the Tenda Nova MW6 uses its own network segment different from my router. My router has the gateway IP 192.168.1.1 but the Tenda Nova has 192.168.5.1. If I connect my phone to NOVA_XXXX, it will get an IP 192.168.5.80 via DHCP. If I set a static address for my phone, say 192.168.1.80, Tenda WiFi app will not see NOVA_XXXX.

I also played around with the Static IP option in the setup wizard. I tried the following:

IP address: 192.168.1.2
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
DNS: 8.8.8.8
(Here, the prompt "Connecting..." will stay on as expected and nothing happens)

IP address: 192.168.5.2
Subnet mask: 255.255.255.0
Gateway: 192.168.5.1
DNS: 8.8.8.8
(Here, NOVA_XXXX will lose internet connection because it has different segment from my router)

IP address: 192.168.5.2
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
(The app shows a toast message that mismatched segments is not allowed)

It is clear that Nova still responds to the app when I change the Static IP config in the setup wizard. But how come I cannot set the SSID and passphrase? It still bugs me.
