How to use a eventStoreConnectionString in the NodeJS Client?

Hi, I’m totally new to EventStore.
We’re trying to play around with clients in Jupyter Notebooks with Node.js (TypeScript) as Kernel.
Anyway, the official repo EventStore/EventStore-Client-NodeJS: A NodeJS client for Event Store ( only provides a basic example.
How do I use a connection string to connect the client?

Best wishes,
