Hi all -
Currently, I have an Ext.Window being added to a tab. I would like to use Ext.air.NativeWindow instead of Ext.Window. Could you please modify the following code to reflect the changes that I need to make:

Code:
    
var win = activeTab.add({
        xtype: 'window',
        id: 'window1',
        title: 'title1',
        closable:true,
        closeAction:'close',
        width:'auto',
        autoHeight: true,
        height:'auto',
        layout:'fit',
        constrain: true,
        constrainHeader: true,
        html:block_properties,
        defaultButton: activeTab.id,
        stateful: false,
        manager: myWindowGroup
    });
