passint identifiers to deletePersonalData() if i call the API from an iframe

[VitaliiLitkevichVL]

I read this document:
https://github.com/InteractiveAdvertisingBureau/USPrivacy/blob/master/CCPA/Data%20Deletion%20Request%20Handling.md

I don't understand where I get identifiers to pass them to deletePersonalData() function

} catch (ignore) {}

if (json.__tcfapiReturn) {

// should be executed at window scope
deletePersonalData();

} // else this is some message we don't recognize

}, false);
