Hi All,
I am new here.
I just started to work with Godot and got a strange problem.
I made a C# Godot VS solution. Added C# library where I am using System.Net.Http.HttpClient to connect to Firebase Auth.
everything worked fine until I convert it to HTML 5.

When I run my Html5 under localhost I got this. As I understand WebAssembly can not find System.Net.Http.dll. I have tried all possible variants of build but no difference.

I would greatly appreciate any help.

Only WebRTC works in HTML5 exports.

Edit:
I never worked with Firebase from HTML5 Secure Context.
But they do have JavaScript API. So maybe you can use them?
