Is there any simple way, on WiFiManager, to check whether there are wifi credentials saved or not?

I have an ESP8266 connected to a button. If I press the button upon esp's startup it will do: wifiManager.resetSettings() and wifiManager.autoConnect("AutoConnectAp").

Besides the button, I would like to have another option: if there are no previously saved settings it would launch the autoConnect function. To do so, I would use an IF LOOP to check that there are no saved settings and launch the WiFiManager AP mode for configuration.

Thank you very much in advance!

The following will output the saved values, if any:

 Serial.println( WiFi.SSID() );
 Serial.println( WiFi.psk() );

You can test if they are null/empty as you wish :)
