Creating temp table in Javascript Icon

Hey, so I recently called an api within a javascript Icon. I would like to create a temp table and populate it with the api data. I am unsure on how to create a temp table and populate it. I found these functions. I attempted to create a schema, it runs but does not do anything. Any advice would be great on creating and populating a temp table so that I can inner join on my current query. Thanks!

P.S. I have been also using these functions but I do not see any changes when I run the script.

registerSchema();

setSchemaSqlTable();

buildSqlTable()
