SAPUI5 Smartable not showing the inital fields - sapui5

Question

I am trying to build a simple smarttable, using a CDS with annotation, I expect the columns to be displayed automatically but no column or selection field are displayed automatically. When I try to create a report with fiori element it is working fine but not with my freestyle app and smarttable. What is missing ?
#AbapCatalog.sqlViewName: 'ZTEST_CDS_SHP'
#AbapCatalog.compiler.compareFilter: true
#AbapCatalog.preserveKey: true
#AccessControl.authorizationCheck: #CHECK
#EndUserText.label: 'Test Shipment view'
#VDM.viewType: #CONSUMPTION
#VDM.private:false
#Search.searchable: true
#UI.headerInfo: { typeName: 'Order', typeNamePlural: 'Orders' }
#OData.publish: true
define view ZTESTV_CDS_SHP as select from ZRDCV_CDS_SHIPMENT
association [0..1] to ZTESTV_CDS_DCHELP as _DCValueHelp on $projection.DcSite = _DCValueHelp.Werks
association [0..1] to makt as _ArticleValueHelp on $projection.Article = _ArticleValueHelp.matnr and _ArticleValueHelp.spras = $session.system_language
{
#Search.defaultSearchElement: true
#UI.selectionField: [ { position: 10 } ]
#UI.lineItem: [ { position: 10, importance: #HIGH } ]
key shipment as Shipment,
#UI.selectionField: [ { position: 20 } ]
#UI.lineItem: [ { position: 20, importance: #HIGH } ]
key exidv as Hu,
....
here is the XML view

Answer 1

Actually, I found the Annotation model in /IWFND/MAINT_SERVICE transaction, by selecting the service, then service implemetation button and annotation model button.
I have added the annotations property in settings with the reference to the array which contains the annotation model. Note that in my case, annotation model is ZTESTV_CDS_SHP_CDS_VAN, when it usually ends by ANNO_MDL.
{
"dataSources": {
"mainService": {
"uri": "/sap/opu/odata/sap/ZTESTV_CDS_SHP_CDS/",
"type": "OData",
"settings": {
"odataVersion": "2.0",
"annotations": [
"ZTESTV_CDS_SHP_CDS_ANNOTATION"
],
"localUri": "localService/metadata.xml"
}
},
"ZTESTV_CDS_SHP_CDS_ANNOTATION": {
"uri": "/sap/opu/odata/IWFND/CATALOGSERVICE;v=2/Annotations(TechnicalName='ZTESTV_CDS_SHP_CDS_VAN',Version='0001')/$value/",
"type": "ODataAnnotation"
}
}
}
