1080          * Use this variant if you want to pass the `description_hash` to the invoice.
1081          *
1082          * `invoice_expiry_delta_secs` describes the number of seconds that the invoice is valid for
1083          * in excess of the current time.
1084          *
1085          * You can specify a custom `min_final_cltv_expiry_delta`, or let LDK default it to
1086          * [`MIN_FINAL_CLTV_EXPIRY_DELTA`]. The provided expiry must be at least [`MIN_FINAL_CLTV_EXPIRY_DELTA`].
