How to send approval notifications to custom approvers field
I have a custom user pick list created for approval purposes. This list has been configured into an approval workflow and the workflow works. The issue is the approvers that are in this custom list do not get email notifications that they need to provide approval. When I tried to add this user list to the approval customer notification, I only get 3 options to choose from (refer to the screenshot). How can I set it up so that the people in this list get email notifications?
Thank you!
