Is it possible to establish a communication bridge between the web app and the android app at runtime (like a postmessage channel)?

vue.js

I wrapped a Vue js web app using android to make it TWA(Trusted Web App).

Now I want to send firebase_token and other data from the Android part to the webapp in TWA. As all the Apis are on a web app and I don't want to call any API in Android.

In WebView we can send data from Android to the webapp using "WebViewController.evaluateJavascript()" but I don't know how can i send data from my Android(java) to web app.

What I have tried:

I implemented my own LauncherActivity and override getLaunchingUrl() to add extra parameters to the URL.But its working in runtime.
