Is it possible to make Note To Approver field mandatory while registering new supplier?

Hi Team,

We are working on the VB Studio where in we wanted to make the Note to approver filed mandatory on the supplier registration page.

We are following below document -

Document says to copy the default business rules using drawer icon.

But when we check it, we are not able to see that icon, can someone please guide ?

Regards,

Neeraj.
