How Do I Make A Pi Pico W Connect To A Network With Wps? - micropython

Question

First time using Stack overflow so I'll do my best to explain.
TLDR - HOW DO I MAKE A PI PICO W CONNECT TO A NETWORK WITH WPS?
I'm making a thing, that basically checks whether the value of a particular stock has gone up or down and lights up green or red LED's based on whether the price is up or down. That's all well and good, but to do this it needs to connect to wifi, and being that the thing I'm making has no screen, or keyboard, all we have to accomplish this is the LED's (for the device to communicate with us) and whatever button I put on there.
My plan was to have the device look at a file called "your_wifi_details.txt" for the SSID and pass, and if it finds them, connect - if nothing is there, or if it cannot connect using those details, it is to enter "WPS mode" where the lights will flash, and the user presses the WPS button on their router then presses a button on the device.
Everything is wired up and working perfectly aside from I cannot work out how to get WPS to work on a Pi Pico W. I think I've gotten really close, but i'm getting the error "'CYW43' object has no attribute 'scan_wps'"
(The lines of code are:
# If the button is pressed, scan for WiFi networks that support WPS
if not button.value():
sta_if.scan_wps()
# Connect to the first WiFi network that supports WPS
sta_if.connect_wps()
)
Then it goes on to connect to the API's and such to get the stock price and from there everything is good.
Literally everything works, if I manually go into the "your_wifi_details.txt" and put in a correct SSID and password, we're golden, but I can't have users required to download thonny and connect to the device and edit files and yada yada... so I am really hoping this WPS thing can work.
This is the first 'proper' program i've written since starting to learn python so apologies if this is a stupid approach, it's taken a lot or time and confusion to get this far but it's so nearly working, I just need a little help over the finish line so if anyone has faced this problem or can help me toward a solution I'd be super grateful
Here's excerpts from the relevant bits of code that are connected to the problem. There's a lot of "print" debugging commands so I can see in the terminal in Thonny where the program is at and what it's doing, obviously in the final use case there won't be a screen or keyboard so all that stuff will be taken out once development is complete:

# Print the WiFi connection status in the terminal so I can see if it worked
