ESP8266 and WiFiManager use as AP instead of WiFi client


I'm not sure if this is the correct place to ask this, my apologies if it is not.

I would like to use an ESP8266 to control a strip of SK6812 LEDs. I downloaded this - GitHub - eighthree/Simple-LED-Strip-Controller: ESP8266 Based LED light strip controller via a web browser and it works great!

My issue is that I want the ESP to act as an access point, instead of joining it to an existing network. I've tried commenting out line of code which ultimately leads to me breaking the entire program.

I don't necessarily need the captive portal, but I wouldn't mind having it still functional. Is there a way I can tell the WiFi Manager to skip the join another network and just use the AP mode it starts in?

Thank you.
