Official WebGL platform support

Hello!

I've been testing the WebGL build for a small personal project, but I have ran into an issue, and I'm not sure whether its an problem with my setup or something else entirely.

I am currently using Windows 10, on Unity version 2020.3.27f1. I believe I am on the latest package version, 2.4.0-exp.5

Firstly, the way I installed the WebGL build was by manually editing the manifest.json file of my project so that the webrtc dependency looks as follows:

com.unity.webrtc": "https://github.com/Unity-Technologies/com.unity.webrtc.git#experimental/webgl-platform"

This seemed to install the right version, so I went ahead and setup a game controller object in an empty scene and added a script setting up a peer and opening a data channel like this:

Code (CSharp):

1. Debug.Log("RTC config set up");
2. // Create local peer
3. Debug.Log("Creating local peer");
4. localPeer = new RTCPeerConnection(ref configuration);
5. localPeer.OnIceCandidate = localPeerOnIceCandidate;
6. localPeer.OnIceConnectionChange = localPeerOnIceConnectionChange;
7. localPeer.OnDataChannel = onDataChannel;
8. Debug.Log("Creating Data channel init");
9. RTCDataChannelInit conf = new RTCDataChannelInit();
10. Debug.Log("Creating Data channel");
11. localChannel = localPeer.CreateDataChannel("data", conf);

When I run this on a compiled WebGL build with a webserver, it seems to setup the peer and open the data channel with no problems. When I attempt to do this in the editor play mode though, Unity crashes, and the Editor.log reports the following:

Code (CSharp):

1. Received signal SIGSEGV
2. Stack trace:
3. 0x000002603034f819 (Mono JIT Code) (wrapper managed-to-native) Unity.WebRTC.NativeMethods:ContextCreateDataChannel (intptr,intptr,string,string)
4. 0x000002603034f72b (Mono JIT Code) [Context.cs:211] Unity.WebRTC.Context:CreateDataChannel (intptr,string,Unity.WebRTC.RTCDataChannelInitInternal&)
5. 0x000002603034f1f3 (Mono JIT Code) [RTCPeerConnection.cs:703] Unity.WebRTC.RTCPeerConnection:CreateDataChannel (string,Unity.WebRTC.RTCDataChannelInit)

I can still work on this thankfully, but I'd like to be able to test my code from the editor instead of having to wait for a build to finish. What should I do to resolve this? I have attached the editor log as a txt file to this post, please let me know if there is anything else I can provide. Thank you for your time!
