How to restrict on Approval Task Details the Camera icon (Button)

Hi Team,

I have a business requirement to prevent users (such as the requisition preparer and those in the approval list) from accessing the "Approve PO" function and from using the "Reassign" task. This ability should be limited solely to IT users.

How can I restrict this from a security perspective (role/privilege)?

Option 1: Prevent users from drilling down into task details or using the camera icon.

Option 2: Hide the "Reassign" task.

Could you please provide further details on implementing each option? Or any other valid way.

BR
