How to test an Interactor Organizer with Minitest

First off, I am using the Interactor Gem. (You should check it out if you haven't. Pretty cool lib)

Let's say I've got an Interactor::Organizer as follows:

class InitiateImport
  include Interactor::Organizer

  organize CreateImport, QueueImport
end

And I've also got two Interactors as follows:

class CreateImport
  include Interactor

  def call
    import = Import.create()
    if import
      context.import = import
    else
       context.fail!(message: 'import failed!')
    end
  end
end

and

class QueueImport
  include Interactor

  def call
    unless QueueHandler.perform_later(context.import.id)
      context.fail!(message: 'Queue broke!')
    end
  end
end

BIG QUESTION - How do I -- using Minitest -- test that organize is being called on InitiateImport with the argument [CreateImport, QueueImport]

assert_send will let me verify that organize is being called, but it won't let me verify what arguments I pass it. Something like this:

class InitiateImportTest < Minitest::Test  
  def test_organize_called
    InitiateImport.new(file: file)

    assert_send([InitiateImport, :organize, [CreateImport, QueueImport]])
  end
end

I found this question / answer from nearly 3 years ago, but it didn't provide much clarity for me. Maybe it's in there and I'm just missing something?

I also realize that I could just call the organizer with valid param data such that it passes and I verify the output from there, however I've already got those two classes under test and I'd basically just be exercising the same functionality twice. I'd really like to just verify method invocation and arguments if possible.

Any help or suggestions would be greatly appreciated.
