How can I hide an assignment action button on a process folder?

Hello, 

You can hide any assignment action using action visibility rules on an assignment configuration extension. This can be done in the the following way: 

Note: Editing the Assignment Configuration Extension will apply the visibility rule globally. Therefore, it will hide the "View" assignment action button for every project. 

1)Create assignment configuration extension in a designer folder. 

Select CREATE DATATYPE/INTEGRATION > CONFIGURATION EXTENSION > Add Entity Actions and Configurations > Type Name > Select Dropdown > Assignment [DecisionsFramework.ServiceLayer.Services.Assignments.Assignment]

2) In Assignment Configurations select All > Action Visibility Rule > ‘Give Rule Name’ > Create

3) Set Action Visibility Rule. Action.Name  Equals <Insert action you want to hide>  (Ex. Action.Name Equals View)
