SecurityException when binding to PostMessageService in TWA integration

Description:
I'm integrating a Trusted Web Activity (TWA) into my Android app and trying to enable postMessage communication. However, I'm encountering the following issue:

Crash Log:
java.lang.SecurityException: Not allowed to bind to service Intent { cmp=com.emofid.rnmofid/androidx.browser.customtabs.PostMessageService }

This happens after I added the following to my AndroidManifest.xml:

In my code, this line returns false and the postMessage connection never succeeds:
boolean result = mSession.requestPostMessageChannel(URL);

Dependencies Used:
implementation "androidx.appcompat:appcompat:1.6.1"
implementation "androidx.browser:browser:1.7.0"
implementation "com.google.androidbrowserhelper:androidbrowserhelper:2.5.0"

Expected Behavior:
The call to requestPostMessageChannel() should return true, and the message channel should be established.

Actual Behavior:
The app crashes with a SecurityException related to PostMessageService, or requestPostMessageChannel() returns false when the service is not declared.

Steps to Reproduce:

Integrate TWA using the dependencies above.
Add PostMessageService to the manifest.
Attempt to call requestPostMessageChannel().

Additional Notes:

Digital Asset Links (DAL) verification is confirmed and working.
TWA launches correctly and shows content.
Issue occurs consistently when attempting to establish postMessage communication.

The TWA is created by BubbleCLI.
