Send notification to Payables team for Supplier created invoices

Summary:

Is there any way to send notification (email and in-app/bell) to the Payables team whenever supplier create invoices in supplier portal (Invoice Approval not enabled)?

Content (please ensure you mask any confidential information):

Currently if supplier create invoices in Supplier Portal, the behaviour if Invoice Approval is enabled:

• For non-PO invoice, only the Requestor will be "notified", since the Requestor needs to approve.
• For PO-based invoice, there's no notification upon invoice creation in the system.
  

I've done some assessment on customizing the FinApInvoiceApproval BPM task based on Doc ID 2820193.1. But this will only get triggered if Invoice Approval is enabled.
