Connecting AP guest network to Router guest network

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello guys,
I have a network with:
1.gateway router ( Redmi AC2100 with OpenWRT 21.02) and an
2.Access point (TP-Link P-Link TL-WA901N/ND v4 with Openwrt 18.06)

I have configured Guest WiFi on router following this tutorial , and same on AP following this tutorial for dumb AP.

On both I have same LAN which is great for the regular WiFi, but for the guest WiFi both make their own separate networks (192.168.89.0/24 in my case). Is there a way to have Access point connect to the router and use Guest network DHCP of the router for it's own guest network?

Reason I want this is so that I can see all DHCP leases on one spot ( in my main gateway router).

Thanks

You should get all devices on stable (21.02.5) first.

2.4 main wifi <-- WDS --> TL-WA901N/ND v4
2.4 guest wifi <-- WDS --> TL-WA901N/ND v4

Whether or not the TL-WA901N/ND v4 can handle 2 WDS I do not know. Save all your configs first. Get second opinion.

It's a 4/32 device.
