How to hide 'new' button in case list view of CSM workspace: Australia version

[ShankyGrover]

Hi Experts,

My organization want to limit the access of creating cases for the internal users based on specific group/role. We are on Australia upgrade and using CSM workspace. 

Please find the attached screenshot for better understanding of my query. I want to hide the option 'new' for specific roles and group. 

We could have done at the ACL level but we do not want to touch those because hiding this option for specific people would suffice our requirement. 

What is done till now?
In application menu > Now experience framework> Declarative Actions> List actions > I found one record having:

Action label: New

Action name: create-new-uxf

Application: Customer Service Case Types

Table: Global

Instead of tweaking the Action Exclusions related list directly, I tried de-activating the above record to verify if it is actually linked with the button configuration and hide it once for all users but it didn't work as expected. 

Please could someone check and assist me further on this matter? 

Thank you.

@ShankyGrover ,

The Declarative Action which you are referring is not the actual declarative action rendering in the Case list in CSM Workspace.

Please open the following sys_id from the List Actions related list: 17c13e7273131010a0a79329faf6a794.

Try making this action Inactive and check whether the change is reflected in the Case list.

Then, add the required Exclusions for this record under the Action Exclusion related list.

If my response finds helpful to you, mark it as helpful and accept the solution.

Thanks.,

Dinesh
