Can i create a vectorSearch index with createSearchIndex command?

Hey! I use Mongoose and for some reason, the client I receive does not have the createSearchIndex function on it.
I managed to sort it out with the createSearchIndexes function.

const client = mongoose.connection.getClient();
const vectorSearchIndexCommand = {
  createSearchIndexes: collectionName,  // Name of   our collection
  indexes: [
    {
      name: searchIndexName,
      type: 'vectorSearch',
      definition: {
        fields: [
          {
            path: "embedding",
            type: 'vector',
            numDimensions: 1536,
            similarity: 'cosine',
          },
        ],
      },
    },
  ],
};

await client.db().command(vectorSearchIndexCommand);
