N/datasetLink with Dataset Builder Plug-In: How to display the data after linking the sets?

Question

Code example below... After creating my linkedDataset how do I display it? I understand it has to do something with the context.dataset but I cant get it to work. I missing something... Any ideas?

var salesRebatesData = datasetLib.load({ id: 'custdataset30' });

var rebatePlansData = datasetLib.load({ id: 'custdataset29' });

var srGroupCode = salesRebatesData.getExpressionFromColumn({ alias: 'entitycustomercustentity_pls_uk_customer_group_codename' });

var rpGroupName = rebatePlansData.getExpressionFromColumn({ alias: 'custrecord_pls_cust_grpname' });

var myDatasetLink = datasetLinkLib.create({

    datasets: [salesRebatesData, rebatePlansData],
    expressions: [[srGroupCode, rpGroupName]],
    id: 'sales_rebates_dataset'

});
