Unreal Engine Millicast plugin fails to package on Android

[Kanermi]

Hi! I'm trying to package a project with the Millicast Publisher and Millicast Player plugins on Unreal Engine 5.3, but it fails with the error messages:

• Plugins/MillicastPlayer/Source/MillicastPlayer/Public/MillicastSignalingData.h(17,10): fatal error: 'api/peer_connection_interface.h' file not found
• Plugins/MillicastPublisher/Source/MillicastPublisher/Public/MillicastWebRTCInc.h(28,10): fatal error: 'api/media_stream_interface.h' file not found

It can be packaged on Windows, though. So, I guess, it's an android related issue.

Here is the full log:
