    3. Insert the overrides_custom.css file under this folder. To do this, please right-click on the folder, --> choose Add resource -->  File --> CSS. Add the file that is present in the case attachments.
    
    4. In the overrides_custom.css file, we have added the below content:
        
        #close.button.capsule.up.last
        {
            display: none;
        }
