Attach Documents to Supplier Bank Accounts – attachment option not visible in Classic UI

Hello,

We enabled the Attach Documents to Supplier Bank Accounts opt-in in the Suppliers offering. The Approve Internal Changes on Supplier Profile for Classic UI feature is also enabled with the Bank accounts choice selected.

However, when we create or edit a supplier bank account through the classic Edit Supplier page, we don’t see any option to add supporting documents or attachments for the bank account.

Could you please confirm:

1. Are there any additional setup steps or profile options required for this feature?
2. Where exactly should users add the supporting document in the Classic UI flow?
3. Should the attachment option appear while creating a new bank account, only after the bank account is created, or in a different action/menu?
