<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">   
<modal name="advanced_inventory_modal">  
     <fieldset name="manage_note">
         <argument name="data" xsi:type="array">        
             <item name="config" xsi:type="array">
                 <item name="label" xsi:type="string" translate="true">Manage Note</item>
