### Describe the bug

I want to hard delete items from a backend amplify @model generated DynamoDB table which is linked to Datastore client on the my frontend mobile app. I don't think this is possible without accessing Dynamo DB directly from a lambda - and this could cause sync issues with Datastore.

If this is correct, then my next option is filter on the _deleted flag so that the deleted items are never received in my local datastore in my observeQuery. 

However, when I try to do this: 

    // Configure DataStore to exclude deleted items
    DataStore.configure({
      syncExpressions: [
        syncExpression(GeofenceEvent, () => {
          return (geofenceEvent) => geofenceEvent._deleted.ne(true);
        }),
      ],
    });

I get the error: Property '_deleted' does not exist on type 'V5ModelPredicate<LazyGeofenceEvent>'.

If I try to add _deleted to the schema, I get: type ModelGeofenceEventFilterInput has already a field with name _deleted. 

How do I access the _deleted flag in syncExpression? Is it possible and if not - what other options do I have?




### Expected behavior

Items should be filtered from observeQuery if the _deleted flag is set, and syncExpression is configured to filter these items out. 

### Reproduction steps

Add this code to a datastore with the above schema

    // Configure DataStore to exclude deleted items
    DataStore.configure({
      syncExpressions: [
        syncExpression(GeofenceEvent, () => {
          return (geofenceEvent) => geofenceEvent._deleted.ne(true);
        }),
      ],
    });

### Code Snippet

```javascript
// Put your code below this line.
Schema & observeQuery code below for reference:

schema.graphql
type GeofenceEvent
  @model
  @auth(
    rules: [
      {
        allow: public
        provider: identityPool
        operations: [create, update, delete, read]
      }
      {
        allow: private
        provider: userPools
        operations: [create, update, delete, read]
      }
      {
        allow: public
        provider: apiKey
        operations: [create, update, delete, read]
      }
    ]
  ) {
  GeofenceName: String! @primaryKey(sortKeyFields: ["DeviceId"])
  DeviceId: ID!
  EventType: String!
  updatedAt: AWSDateTime!
}

   // Subscribe to changes for a specific geofence
    const subscribeToSpecificGeofenceEventUpdates = (geofenceName: string) => {
      let previousEventTypes: { [key: string]: string } = {};

      DataStore.observeQuery(GeofenceEvent, (ge) =>
        ge.GeofenceName.eq(geofenceName)
      ).subscribe((snapshot) => {
        const { items, isSynced } = snapshot;
        console.log(
          "observeQuery: received for geofence:",
          geofenceName,
          items,
          isSynced
        );
        if (isSynced) {
          // Handle the updated geofence events
          items.forEach((event) => {
            // console.log(`Device ${event.DeviceId} has event type: ${event.EventType}`);
            const previousEventType = previousEventTypes[event.DeviceId]; // TO DO - should I be using previousEventType store??
            if (previousEventType !== event.EventType) {
              console.log(
                `>>>>>>>>>>>>>>>>>>>>> Device ${event.DeviceId} has NEW event type: ${event.EventType}`
              );
              // Update the previous event type for the device
              previousEventTypes[event.DeviceId] = event.EventType;
            }
          }); 
        }       }); 
    }; 
  }

```
