I have a friend using JetBrains Rider and when he uses Jump To Definition (F12) he can see the method signature and implementation! I tried installing Rider but it is not yet supported on my ARM64 Mac. Is there anyway I can view Unity method implementations using VSCode or VSCode Insiders?

For example, if I have the following call, I click Translate

transform.Translate(Vector3.forward * Time.deltaTime * zSpeed);

Then I press F12, which opens Transform.cs but only shows the method headers. The implementations are missing

// Summary:
//     Moves the transform by x along the x axis, y along the y axis, and z along the
//     z axis.
//
// Parameters:
//   x:
//
//   y:
//
//   z:
//
//   relativeTo:
public void Translate(float x, float y, float z);

// comments removed for brevity...
public void Translate(float x, float y, float z, [DefaultValue("Space.Self")] Space relativeTo);

// comments removed for brevity...
public void Translate(Vector3 translation);

// comments removed for brevity...
public void Translate(Vector3 translation, [DefaultValue("Space.Self")] Space relativeTo);

// comments removed for brevity...
public void Translate(float x, float y, float z, Transform relativeTo);

// comments removed for brevity...
public void Translate(Vector3 translation, Transform relativeTo);

Any help is greatly appreciated!

Per a comment, I tried Cmd+F12

But then it says "no implementation found"

I'm stuck!
