1. Let calendar be the this value.
2. Perform ? RequireInternalSlot(calendar, [[InitializedTemporalCalendar]]).
3. Assert: calendar.[[Identifier]] is "iso8601".
4. If Type(fields) is not Object, throw a TypeError exception.
5. Set options to ? GetOptionsObject(options).
6. Let result be ? ISOYearMonthFromFields(fields, options).
7. Return ? CreateTemporalYearMonth(result.[[Year]], result.[[Month]], calendar, result.[[ReferenceISODay]]).
