Incident Priority high tickets can be created only by a particular group

[pravee26]

Creating new Incident tickets with high priority can be done only by 'service Desk' group members.If any other support group members attempt to create priority high incident tickets then pop up should be displayed stating 'you dont have access to create this ticket' and ticket should not be created. How to achieve this? I wrote this ACL
