@vladisam1 Hi Vlad, is there a separate SharePoint list? or when you say SharePoint list you mean the SharePoint document library. If it's a SharePoint document library , I think the previous answer would fit for you. Otherwise you would need choose the approver value from SharePoint list column.
Please mark my reply as a solution if you think it helps.
Thank you.
