Wifi-setup-web-ui - change

hi, i need to change the lib so that it gives me a ssid return, whenever i open the captive portal.
that way I can know on which network the esp8266 is configured.
could you help me?

Do you want to know ESP8266 Access Point name?

no, i would like to get the ssid information, in which ssid esp8266 was last configured … being a new field on the web page, or pull and show in the field that configures the ssid.
