Customers may observe an extra unnecessary Accept button in the customer's App/Reject Tab.
It appears on the top level and also when clicking into individual requests. But the Accept button does not seem to be in the Admin guide. See the below image on the customer's UI and admin guide.

To clarify, The Accept button is enabled if the following checkbox is enabled in settings > website > Catalog Behavior
This is not regular action taken by approvers so it is not part of the main topics for approvals in our document. However, this setting explanation is available in the admin guide and it gives good context on what it is used for.
