How to change the default value 'Accounts Payable' in AP Invoice Approval Request Information

Hi,

     We created AP Invoice Approval setups using AME. Now, we created Invoice and initiated for approval. Then the Requester received mail to take action. In the mail, there is 'Request Information' link along with 'Approve' and 'Reject'. The default value it is showing is as 'Accounts Payable'. How to change this value?

When we click on above 'Request Information' link a new mail will open with 'Request more information from' as 'Accounts Payable' as shown below. I need to change this to custom value REQ_INFO_TEAM who is actually a FND USER we created

As shown below, when we open the notification from Application, it is not showing any participants
