react-native - Push to talk with Firebase [closed]

I am searching about how to implement the Push-to-talk function for React native app using Firebase.

However, after a few hours of researching, I didn't find any tutorial how to do it. There are a lot of posts and blogs show me how to implement the Push Notification using Firebase but not Push-to-talk.

If you know any useful links, blogs, and so on, please let me know.

Thank you in advance!
