Hello, I have created a Zoom app by cloning the Zoom sample app repository(zoom/zoomapps-texteditor-vuejs). I have added firebase auth in the same app. The app works perfectly fine on Mac machines but gives firebase errors on Windows.  
By following some of the forum threads, I have added these urls to domain allow list:  
[securetoken.googleapis.com](http://securetoken.googleapis.com)  
[firebaseinstallations.googleapis.com](http://firebaseinstallations.googleapis.com)  
[firebase.googleapis.com](http://firebase.googleapis.com)  
[identitytoolkit.googleapis.com](http://identitytoolkit.googleapis.com)

I have also added following CSP headers in index.ts of zoom/zoomapps-texteditor-vuejs/server:  
app.use(  
helmet({  
frameguard: {  
action: ‘sameorigin’,  
},  
hsts: {  
maxAge: 31536000,  
},  
referrerPolicy: {  
policy: ‘same-origin’,  
},  
crossOriginEmbedderPolicy: false,  
contentSecurityPolicy: {  
directives: {  
‘default-src’: [“‘self’”],  
‘connect-src’: [  
“‘self’”,  
‘[https://identitytoolkit.googleapis.com](https://identitytoolkit.googleapis.com)’,  
‘[https://firestore.googleapis.com](https://firestore.googleapis.com)’,  
‘[https://zoom.us](https://zoom.us)’,  
‘https://_.zoom.us’,  
'https://_.googleapis.com’,  
],  
‘img-src’: [  
“‘self’”,  
‘data:’,  
‘[https://www.google.com](https://www.google.com)’,  
‘https://_.google.com’,  
'https://_.gstatic.com’,  
],  
‘script-src’: [  
“‘self’”,  
“‘unsafe-inline’”, // Only if you’re using inline scripts (consider removing in production)  
‘[https://appssdk.zoom.us](https://appssdk.zoom.us)’,  
‘[https://www.gstatic.com](https://www.gstatic.com)’,  
],  
‘style-src’: [  
“‘self’”,  
“‘unsafe-inline’”,  
‘[https://fonts.googleapis.com](https://fonts.googleapis.com)’,  
],  
‘font-src’: [“‘self’”, ‘[https://fonts.gstatic.com](https://fonts.gstatic.com)’],  
‘frame-src’: [“‘self’”],  
},  
},  
})  
);

Still getting errors like(While testing locally):  
a393-103-215-148-71.ngrok-free.app/:1 Refused to load the image ‘[https://www.google.com/images/cleardot.gif?zx=yzoh3m6oc8mm](https://www.google.com/images/cleardot.gif?zx=yzoh3m6oc8mm)’ because it violates the following Content Security Policy directive: “img-src ‘self’ data: [https://4aa5-103-215-148-68.ngrok-free.app](https://4aa5-103-215-148-68.ngrok-free.app)”.

index.e5864361.js:219 [2025-05-06T09:13:07.456Z] @firebase/firestore: Firestore (10.14.1): Could not reach Cloud Firestore backend. Connection failed 1 times. Most recent error: FirebaseError: [code=unavailable]: The operation could not be completed  
This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

Had added some logs while I was debugging, error occurred at this line:  
const querySnapshot = await getDocs(userQuery);

Any help would be greatly appreciated, stuck at this point since a long time.
