Remove or hide Button from form view

Hi All

I’m tired of removing or hiding the button from the form view, but it’s no use
how to solve this

frappe.ui.form.on('Sales Order', {
    refresh(frm) {
    setTimeout(() => {
        frm.remove_custom_button('Update Items');
        frm.remove_custom_button('Close', 'Status');
        frm.remove_custom_button('Work Order', 'Make');
        }, 10);
    }
})

Try This:

frappe.ui.form.on('Sales Order', {
	refresh(frm) {
	    setTimeout(() => {
        frm.remove_custom_button('Update Items');
        frm.remove_custom_button('Close', "Status");
        frm.remove_custom_button('Work Order', "Create");
        }, 10);
		
	}
})
