invoice approval on sharepoint list

Hi i need someone advice. I have a sharepoint list where i create an invoice (with attachment - original scan of invoice) and that invoice is send to approval (using power automate). All works fine but i find one big problem for me. If i send an approval request to someon there is link to this invoice on sharepoint and if approver click on it there is a request for permmision for that sharepoint group - and after i approve his request for this group he can view all others documents in this group, but i need to show him only that invoice that i need to approve. Bcs someone can view only his invoice and doesnt need to view invoice from whole organization. So is there any solution to show him only one invoice please to help. Thanks
