How to not show specific issue custom form section to certain Worker license users
I am creating an Issue Custom form wherein I need to restrict access to few worker license users (Agency) users from seeing certain feels on the form. There are confidential details which they are not suppose to see. I do see that there is a grant access option where I can select 'Admin Only' so only users with 'Admin only' access to the issue object will see these fields. This won't work in my situation as the other Planner License users who need to see these details on the custom form will then not be able to see these details as they don't have 'Admin access' on the system or object.
I even tried creating 2 separate issue custom form with the confidential fields added to the 2nd one.. But I didn't see any option in there to hide this custom form from the Issue Details section for Worker license.
Can someone guide me on how best to configure this so that Planner License user can see entire Issue Custom Form details and the Worker License user can only see the section of fields which are applicable for them.
Any help on this will be highly appreciated?
