How to set up an asus rt-ac750 router as a repeater?

Question

ASUS

Answer -> no way.
I wrote to the official ASUS website and the answer came "No, this model doesn't support the repeater mode." That's it.
I drove to El Dorado and returned it safely. I bought a cheaper RT-N12 in a nearby store, it is configured as a repeater easily and simply.
--------------------
I bought ASUS RT-AC750 3 in 1 Router, Access Point, Repeater. I want to use it as a repeater, that is, connect it to a router that is far away and expand the network. I already have an ASUS RT-N12 VP and everything is simple there, I connected - I chose to use it as a repeater - I entered the password and there is an extended network. In the new one (RT-AC750), the repeater function is indicated on the box, but I can’t find it in the settings.
