How to have Similarity algo use the node properties?

If you look at the examples for Cosine Similarity in the docs, you'll see an example of using node properties for similarity calculations:

  MATCH (c:Cuisine)
 WITH {item:id(c), weights: c.embedding} AS userData
 WITH collect(userData) AS data
 CALL gds.alpha.similarity.cosine.stream({
  data: data,
  skipValue: null
 })
 YIELD item1, item2, count1, count2, similarity
 RETURN gds.util.asNode(item1).name AS from, gds.util.asNode(item2).name AS to, similarity
 ORDER BY similarity DESC

The collect takes the node properties (c.embedding) and uses those to calculate similarities between cuisine nodes.
