How to improve a performance of the query to Firebase firestore

Question

I'm facing a problem related performance using Firebase firestore.
The reason is recognized, but the solution is not found.
How do I cope that?

        const snapshot = await db
      .collection("customers")
      .doc(id)
      .get();

The size of a request is not a large, about below 10KB.

There's nothing you can change about the code you shared to improve the performance. Your only options would be to get a faster internet connection (lower latency and/or more bandwidth).

From the screenshot it seems to take 53ms to read the document, which seems pretty reasonably to me at first glance.
