Yup validation with ISO Format in REACT

I am trying to validate date using Yup validation. The requirement is that the ToDate should be greater or equal to the fromDate.

fromDate : ‘2022-02-13T16:31:13.983Z’

toDate : ‘2023-02-01T00:00:00.000Z’

REQUIREMENT

• toDate >= fromDate

        fromDate: Yup.string().required('required.'),
        toDate: Yup.string().required('required')
        .test(
            "fromDate",
            "To Date should be greater or equal to From Date",
            (date) => moment().isAfter(moment(date), 'hours')
          ),

But it seems the logic is quite wrong. . I’d appreciate your help. Thanks.
