Hello, 

I have a list that has an approver column. Each approver needs to have the permission to only  be able to Read and edit list item that has their name on it ( not looking for just to format a view, they shouldn’t have permission to see the other items). On that same list currently I am using item level permission to control the permission  for users that create the item. I also have another permission group with custom design permission level that can read and edit all list items. I am having difficulty finding a way to set the permission for the approver group or the approvers. Does anyone know  how I can achieve this? Thank you for your help.  Note: This is built on Nintex office365 forms and workflow.
