Lifecycle of a google cloud firebase background function?

I've been using the GCP Firebase Functions for about a week now for work.

My question is regarding the lifecycle(dunno if that's the right term) of Background functions.

Say for example I get a CSV file from a bucket

const file = bucket('foo').file('some/file.csv');

after which I download the file and then parse the CSV with some function, and then I send it to firestore.

file.download()

    .then(data => parseCSV(data[0]))

    .then(parsedData => sendToFirestore())

    .catch(error => {

      // handle...

    })

In an HTTPS function, all I would have do to end the function would be to call res.end() or something similar.

But how does a background function register that it should stop running or that it's done?

I would suggest you watch the videos from the official series: firebase.google.com/docs/functions/video-series, in particular the ones titled "Learn JavaScript Promises".
