How can I enable persistence?

I have:

const server = await MongoMemoryServer.create({
  instance: {
    dbPath: '/var/app/.data/example',
    dbName: 'example'        
  }
});

As long as it keeps running it works perfect but if I close the process and re-open it the data is all gone.

I figured it out.

I had to set storageEngine: 'wiredTiger', on the instance configuration also. When I tried it it threw an error because I had previously set the dbPath and it had files in that folder for the other storage engine. So I just deleted .data folder and restarted and it is now persisting.
