Is administrativeArea accepted in componentRestrictions

[pierre-phil]

I've been trying to use administrativeArea to restrict the suggested results to a region of the US.

This works :

 requestOptions: {
      componentRestrictions: {
        country: "us",
      },
    },

but not this :

    requestOptions: {
      componentRestrictions: {
        country: "us",
        administrativeArea: "MN",
      },
    },

nor this :

    requestOptions: {
      componentRestrictions: {
        administrativeArea: "MN",
      },
    },

Won't show any suggestions with this. Am I missing something ?
