How to match specific modifiers of a method?

How to match specific modifiers of a method? In this example I want to match all public methods.

C#

class Bar {
    public static async void Fii() {
    }

    void Foo() {
    }
}

Rule:

language: csharp
rule:
  kind: method_declaration
  has:
    field: modifier
    regex: ^public$

field and kind are different.

language: csharp
rule:
  kind: method_declaration
  has:
    kind: modifier
    regex: ^public$

@HerringtonDarkholme Would it be possible to generate a warning or error if an invalid kind or field is used?

@dotjpg3141 good idea. Let me create an issue to track it.
