Workflow Error-Unable to fetch public identity for governance group members

I tried to iterate the list of identities, and used these identities as a recipient in the form using for loop and email is also getting triggered but for each iteration a new form instance/approval is getting created which is not helpful here.

Is there any way we can use same form instance/approval which can be sent to all the list of identities and if anyone of them will get approved and other approvers wont able approve it again and the form gets expired.
