禁用麦克风权限

请问楼主，建立连接时如何禁用麦克风权限申请，我在官方提供的代码基础上注释掉下面两行代码，但是在建立连接的时候还是会申请麦克风权限。
[self createAudioSender];
[self createVideoSender];

Start by tracing the connection setup around the two Objective-C calls shown in the issue: createAudioSender and createVideoSender. Check which remaining connection path requests microphone access after those calls are commented out. Done means establishing a connection no longer requests microphone permission while the intended video behavior remains unchanged.
