How to register an overloaded method with an array type using mono_add_internal_call?

[ffbh123456]

c++

void test_array(MonoArray* array);

c#

[MethodImpl(MethodImplOptions.InternalCall)]
public static extern void Test1(Vector2[] array);

To register the method, what should I replace for the "?????" in mono_add_internal_call?

mono_add_internal_call("Namespace.ClassName::Test1(?????)", (void*)test_array);
