Error using nodejs to create vector search index on mongodb 7

I'm porting a RAG pipeline from GenAI-Showcase that was using Atlas to a mongdb local instance to the LLM.

Following https://www.mongodb.com/docs/compass/current/indexes/create-vector-search-index/, I installed node >16.4 and npm mongodb module but it appears that the installed mongodb module is missing a createSearchIndexes context.

Does mongodb 7.0 support vector search index definition ? Is Atlas your only offering that supports vector search ?

Start with atlas-vector-search-quick-start.js at line 30 and inspect the Node.js driver's createSearchIndex call that produces the createSearchIndexes error. Compare the example's assumptions with the reported MongoDB 7.0 local instance and determine whether the command is supported; document the confirmed compatibility or required project changes.
