Bulk way to determine of all paths, which one exists (Possibly in one API Call)

Question

I have an array of strings and want to check which of all those documents exist in my Firestore in two ways:

I am using Node Admin SDK:

import Server from '../../../../firebase/firebase_server_exports';

export const databaseEntryExists = async (paths: string[]): Promise<string> => {
  const promises = paths.map(
    (element) =>
      new Promise((resolve) => {
        Server.db
          .doc(element)
          .get()
          .then((doc) => resolve(doc.exists ? element : ''));
      })
  );
  const results = await Promise.all(promises);
  return results.includes(true) ? paths[results.indexOf(true)] : '';
};

Though this method works nicely, if I have 100 paths, I will be making 100 API calls which doesn't sound a good deal to me. Can someone suggest any Fierstore utility function or something like batch document fetching in order to reduce this to one API call?
