National Insurance Refund Moving abroad

Hello, my partner moved abroad in February 2023. In August 2023, she received an NHS backlog payment bonus, and according to the payslip she paid NI (no PAYE). Is she entitled for a refund on this, since she is since then not UK resident? Can she use that credit towards NI voluntary contributions? Many thanks and best regards
