Azure Communication Services Calling SDK for Unity doesn't support for Video Calling

Question

Hi, I'm developing an immersive application for HoloLens by Unity. I have a requirement of integrate Azure Video Calling feature to the application. Video call should be establishe between HoloLens and PC. I tried this (https://learn.microsoft.com/en-us/azure/communication-services/quickstarts/voice-video-calling/get-started-with-video-calling?pivots=platform-unity) document. But I have encountered few issues and need support to sort them out.

1. I have noticed that there is a new beta release (1.0.0 - beta.2) of Azure Communication Services Calling Unity SDK. But seems the document is not update to match with that version as I got some errors on some methods of the document. 

1. In the 1.0.0-beta.1 version I'm getting an runtime error in the Unity Editor as follows when trying to call. "InvalidOperationException: Unknown error.Azure.Communication.Calling.UnityClient.NativeLibraryHelpers.CheckStatus (System.IntPtr handle, Azure.Communication.Calling.UnityClient.Status value) (at Library/PackageCache/com.azure.communication.calling@9eb4a6f82e64/Runtime/Azure.Communication.Calling.UnityClient/Azure.Communication.Calling.UnityClient.cs:205)Azure.Communication.Calling.UnityClient.OutgoingVideoOptions.set_Streams (System.Collections.Generic.IReadOnlyList`1[T] value) (at Library/PackageCache/com.azure.communication.calling@9eb4a6f82e64/Runtime/Azure.Communication.Calling.UnityClient/Azure.Communication.Calling.UnityClient.cs:12574)AppManager.CallButton_Click () (at Assets/Scenes/AppManager.cs:66)System.Runtime.CompilerServices.AsyncMethodBuilderCore+<>c.<ThrowAsync>b__7_0 (System.Object state) (at <9d9536d9127f4a489d989c7a566aee1c>:0)UnityEngine.UnitySynchronizationContext+WorkRequest.Invoke () (at <120b8d04add741329ccd415c000fb666>:0)UnityEngine.UnitySynchronizationContext.Exec () (at <120b8d04add741329ccd415c000fb666>:0)UnityEngine.UnitySynchronizationContext.ExecuteTasks () (at <120b8d04add741329ccd415c000fb666>:0)"

But after comment below line of the CallButton_Click method,  

" OutgoingVideoOptions = new OutgoingVideoOptions() { Streams = new OutgoingVideoStream[] { cameraStream } }"

then above error disappeared and only audio call  establish. As video call function is the requirement, I kindly expecting support for solve the above issues.

Thanks
