Trouble with aws_auto_scaling_group in InSpec

Hi All,

I am trying to use the aws_auto_scaling_group method in InSpec.

describe aws_auto_scaling_group(name: 'MyASGName') do
    it { should exist }
end

However, when I run it, I get an error saying that the method doesn't exist.

undefined method `aws_auto_scaling_group' for #
<Inspec::ControlEvalContext:0x0000000005c9f2c0>

According to the documentation, this should exist...am I missing something? This is running on the latest version

aws_auto_scaling_group resource (chef.io)

Thanks for any help!
