UI builder client script to hide attachments icon when state is closed

[kiran kumar m1]

I need a functionality in my workspace such that if I close the ticket ,the attachments icon should not be visible , I went to UI builder open the attachments tab wrote a script over there    

function evaluateProperty({api, helpers}) {
// Fetch the current state of the ticket
const currentState = api.state.record['state'];

// Check if the state is 3
if (currentState === 3) {
return false; // Hide the attachment icon
}

return true; // Show the attachment icon for all other states
}

but this seems not working for me , can anyone help in  syntax of this script
