Bank account transfer approval workflow not working as expected for CE

Hi Experts,

We have a Customer requirement to set the approval for the Bank Account transfer(within LE) in cash management and without enablement of the Check box of "Settle through payments" option. 

We have created a separate rule for the Bank account transfer without using the seeded rule of "Auto-Approve". But unfortunately the Workflow notifications are not been triggered for approvals.

If someone had come across or worked on the similar requirement scenario , kindly throw some light and inputs for us to proceed.

Thank you in advance

Regards,

Raja
