Signals is not connected via a static singleton bus (C#).

Question

I'm trying to send signals over a singleton static bus and I'm getting an error:
"SignalBridge.TestSignal" is a type, but is used as a variable. [MiniGames]csharp(CS0118)
Error in Receiver class in the line "SignalBridge.TestSignal += DoSomething"

Signal Bridge:

using Godot;
using System;

namespace Test.SignalBridgeTest
{
    public static class SignalBridge
    {
        [Signal] public delegate void TestSignal();
        [Signal] public delegate void TestSignalWithArgument(int number);
    }
}

Emitter:

using Godot;
using System;

namespace Test.SignalBridgeTest
{
    public partial class Emitter1 : Node
    {
        [Export] public bool enable = false;

        public override void _Process(double delta)
        {
            if (enable)
            {
                EmitSignal(nameof(SignalBridge.TestSignal));
            }
        }
    }
}

Receiver:

using Godot;
using System;

namespace Test.SignalBridgeTest
{
    public partial class Receiver : Node
    {
        public override void _Ready()
        {
            SignalBridge.TestSignal += DoSomething; //ERROR IN THIS LINE
        }

        public void DoSomething()
        {

        }
    }
}
