Is there a WPS button or a digital version for a WiFi 6 router?

This is probably a dumb question, but my old isp had a wps button on the router, and within the routers webpage. This made connecting a powerline adapter a breeze for simply just extending the range, not necessarily just for creating a separate network or two. I’d like to increase just the range, so more or less, as if the router is in the same room, but from across the house. I got it connected for now, but it created two separate band networks; and I know the speeds could be far better than they are now; I’ll still be playing with it regardless, but I thought I’d try to gather some answers in the meantime from others, who have done this already.

How can I go about this? Can I just search my routers ip address and that’ll bring up its webpage and wps will be in the settings? or what can I do? It’s a wifi 6 router, just got my service this past Sunday.
