Firebase – Is there a new FirestoreAdminClient to use now when cloud functions are recommended to run on 2nd gen?

When doing data export from Firestore to a bucket I am following the suggested solution on: Schedule data exports.

Some cherry-picked code from the solution is as follows:

const client = new firestore.v1.FirestoreAdminClient();
...
const projectId = process.env.GCP_PROJECT;
const databaseName = client.databasePath(projectId, '(default)');

return client.exportDocuments({
    name: databaseName,
    outputUriPrefix: bucket,
    collectionIds: []
    })
...

Now, with 2nd gen I know that e.g. project Id instead can be picked up using a pre-defined parameters from firebase-functions/params

But is there a new FirestoreAdminClient that should/could be used to do databasePath() and exportDocuments() with?
