So basically you plug 2 cables from THAT to your asus router and turn on aggregation on your asus ?
Yes.
In the ONR, I chose for it to dial PPPoE for, map to all LAN and Wifi ports, but did not vlan-tag any. I chose to connect LAN1+LAN2 to ASUS; but any are usable since already mapped to all.
In my case, I also set its DMZ Host to point to 192.168.0.2 (so any unsolicited incoming internet traffic falling through the fibre interface gets shifted to fall onto the downstream ASUS later).
And I disabled Wifi altogether.

In the ASUS, I assume you have choice of either 1Gbps WAN or 2.5G LAN-convertible-to-WAN....
(1) On Dual-WAN tab, DO NOT ENABLE Dual-WAN, but you should still be able to choose 2.5G port as primary WAN interface.
(2) On WAN tab, chose to configure your selected primary WAN interface. DO NOT USE PPPoE. If you scroll slightly down, you will now see option to aggregate port appears. On RT-AX86U, the aggregation is on primary WAN port (you chose 2.5G on Dual-WAN tab, right?) AND LAN4.
(3) Any ports that are not part of WAN purpose will now become LAN ports - and that also applicable the original 1Gbps WAN port.
For my use, I chose to assign static IP 192.168.0.2 to my aggregate WAN port with gateway pointing to the ONR's 192.168.0.1. (Remember I set DMZ in ONR above?)

I use the spare ports LAN3+LAN4 on the ONR to connect my AndroidTV and ASTRO. Those devices are safe to leave outside the inner network protected by ASUS, AND, they don't need to burden my ASUS with endless streaming. They can also mop up the remaining Mbps that is not reachable by the downstream ASUS. You can also expand the LAN3+LAN4 by attaching network switch. So now I have 2 layered Intranet.
