Javascript 如何从不同设备连接到firestore上的同一文档？

我有以下职能：

const functions = require("firebase-functions");
const admin = require("firebase-admin");
admin.initializeApp();
const Firestore = require('@google-cloud/firestore');
const db = admin.firestore();

exports.createCollectionByPlayerID = 
functions.https.onCall((data,context) => {
    const citiesRef = db.collection(context.auth.uid);
    let setSf = citiesRef.doc('1SF').set({
        name: 'San Francisco',
        state: 'CA',
        country: 'USA',
        capital: false,
        population: 260
    });
    return "testID"
});

我希望这个函数为每个玩家创建单独的集合（或文档），以玩家ID命名。 当我从一个设备调用此函数时，该函数将使用一个名称创建新集合：

当我从另一个设备调用同一个函数时，该函数将创建另一个具有另一个名称的集合

我需要从不同的设备连接到一个由一个玩家创建的集合，而无需创建新集合

我的java代码：

private void hw_fromFunction() {
    FirebaseUser mUser = FirebaseAuth.getInstance().getCurrentUser();
    mUser.getIdToken(true)
        .addOnCompleteListener(new OnCompleteListener<GetTokenResult>() {
            public void onComplete(@NonNull Task<GetTokenResult> task) {
 if (task.isSuccessful()) {
       String idToken = task.getResult().getToken();

    helloWorldFromFunc(idToken).addOnCompleteListener(new 
    OnCompleteListener<String>() {
        @Override public void onComplete(@NonNull Task<String> task) {}
     });
  } else {}
       }
              });
}

private Task<String> helloWorldFromFunc(String idToken) {
    Map<String, Object> data = new HashMap<>();
    data.put("push", true);
    return mFunctions
            .getHttpsCallable("createCollectionByPlayerID")
            .call(idToken)
            .continueWith(new Continuation<HttpsCallableResult, String>() 
{
                @Override
                public String then(@NonNull Task<HttpsCallableResult> 
task) throws Exception {
                    return (String) task.getResult().getData();
                }
            });
}

//>>>>>>>>>>>>>>>>*****auth***********
GoogleSignInOptions gso = new 
    GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
         .requestIdToken(getString(R.string.default_web_client_id))
//.requestEmail()
         .build();

    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

    mAuth = FirebaseAuth.getInstance();

private void signIn() {Intent signInIntent 
    = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);

    startActivityForResult(signInIntent, RC_SIGN_IN);
}

private void signOut() {
    mGoogleSignInClient.signOut().addOnCompleteListener(this
            , new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    updateUI(false);
                }
            });
}

private void revokeAccess() {
    mAuth.signOut();
    mGoogleSignInClient.revokeAccess().addOnCompleteListener(this
            , new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    updateUI(false);
                }
            });
}

}
