Retrieving saved WiFiManager parameters - Help needed

II have used WiFiManager on a small project using an ESP8266. I want to write details of the SSID to the OLED screen when it is booting up. How can I retrieve the SSID saved in the WiFiManager, and how would I also display the IP address too to the OLED screen ?

The OLED uses the format
updateOLED("Line1", "Line2", "Line3", "Line4");

Thanks in advance

Maybe like this..
updateOLED((WiFi.SSID()), (WiFi.localIP()), "Line3", "Line4");
