+/// player to enable DRM capabilities and communicate with the native side properly.

+/// Example usage:
+/// ```dart
+/// registerDrmCallback(licenseCallback, _playerId);
+/// ```
+///
+/// Note: This function should not be called directly outside the [initialize] method,
+/// and it requires proper configuration and setup of the native C/C++ code to handle
