Module "firebase-admin/firestore" has no exported member 'Filter'

[vixson]

I do not think this class is Exported for usage.

From what I saw on the node_module it was an abstract class

snippets-node/firestore/main/index.js

Line 5 in 7b30935

const { getFirestore, Timestamp, FieldValue, Filter } = require('firebase-admin/firestore');

Please how can this be used in Cloud function?
