ESP32 Preferences library, initialized method

[Thomasx]

Hi

According to the Overview in the Preferences Library documentation (link below) it is stated that

a library method is provided to determine if a key value has been initialized.

What method is this and how does it work? I can't seem to find that info in the documentation.

Thanks!
