Onload Client Script not working in Agent workspace

[Michael_Nash]

I have the below onload Client script and is working perfectly in UI16 however i need the banner to also show in Agent Workspace.

function onLoad() {

    var isEvTruck = g_form.getValue('u_ev_truck');

    if (isEvTruck === 'true') { // Check if the value is a string 'true'

        // Create a banner element

        var banner = document.createElement('div');

        banner.style.backgroundColor = 'lightgreen';

        banner.style.color = 'black'; // You can adjust the text color

        banner.style.padding = '10px';

        banner.style.fontWeight = 'bold';

        banner.style.textAlign = 'center';

        banner.innerText = 'This is an EV Truck!';

        // Insert the banner at the top of the form

        var formHeader = g_form.getFormElement().firstChild;

        g_form.getFormElement().insertBefore(banner, formHeader);

    }

}
