nothing happens on my machine when i try to answer the call

[hchiam]

i'm guessing the code is old and might not work anymore?

when i paste the string of characters and hit "Answer" in the other browser tab, nothing seems to happen for me

i've set up a cloud firestore database with top-level collections banned, calls, messages, and users, and after a few moments i get

@firebase/firestore: Firestore (8.10.1): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds. 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. from main.js

and then FirebaseError: Failed to get document because the client is offline. from firebase_firestore.js

i'm able to use firebase to fetch and save data in other projects, so i don't trust the note about internet connection
