Failed to verify return for AY 2022-23. Can 139(8a) updated return be filed to claim refund?

Dear experts,

Tax payer has failed to verify original return for FY 2021-22 (AY 2022-33) filed under Section 139(4) in December 2022. Last date to verify has elapsed, and now as per the IT department website the return is treated as not filed. And there is no option of condonation of delay in verification shown in the IT department website. 

Tax payer has a refund to be obtained. 

Can updated return under 139(8a) new section be filed now ?

Please advice on the same, how can this return be processed. Thank you
