**Description**  
When implementing live transcriptions, using the transcriptions related delegate calls is causing a linking error.

**Which macOS Video SDK version?**  
1.8.5, 19.1.

**Additional context**

```auto
ld: Undefined symbols:
  _OBJC_CLASS_$_ZMVideoSDKLiveTranscriptionMessageInfo, referenced from:
       in ZoomDelegateSubscriber.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)

```

I see the same problem for `ZMVideoSDKVirtualBackgroundItem`:

```auto
ld: Undefined symbols:
  _OBJC_CLASS_$_ZMVideoSDKVirtualBackgroundItem, referenced from:
       in ZoomTypes-Mac.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
