Debug a standalone Blazor WebAssembly app in VSCode with **watch**

I want to debug standalone Blazor WebAssembly applicaton with watch options in VSCode.

I followed Debug ASP.NET Core Blazor WebAssembly and it works well with breakpoint. However code change does not apply while debugging. But, Run dotnet wtach run --project /Path/To/Project.csproj in Terminal does apply code change. So I suspect launch.json file should be changed to apply watch option.

What should I change to achieve it?

Here is my launch.json, which is auto-generated.

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Ledger.Client.Web",
            "type": "blazorwasm",
            "request": "launch",
            "cwd": "${workspaceFolder}/Client/Web",
        }
    ]
}
