How can I take action on an external supplier registration request pending with the supplier?

Summary: Supplier submitted an external registration request and the approver sent it back for them to make a correction and resubmit. They used the action "Request Information." The supplier did not receive the Oracle email to take action on this request. How can we help the supplier find this request to make the needed correction and resubmit for approval?

Content (please ensure you mask any confidential information): We cannot see who this is pending with in the approval history. We think it should be with the supplier but cannot take any action since the approver requested information from them. The supplier checked their spam and could not find the email notification to take action. Is there a way we can resend the email or send them a link so they can revise their request and resubmit?
