`reasoning_effort: "minimal"` is totally unavailable

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

We're currently unable to set reasoning_effort to "minimal" even on models which support that level.

Excerpt from openai module:
export type ReasoningEffort = 'low' | 'medium' | 'high' | null;
As you can see we have low medium high and "null" (what does this do?) but no option for minimal.

To Reproduce

1. Write some instance of the completions create method
2. attempt to set reasoning_effort to "minimal"

Code snippets

Here's the context in which I'm unable to set the parameter: 

const { choices } = await openai.chat.completions.create({
    model: STRICT_JSON_MODEL,
    messages: [{ role: "user", content: prompt }],
    response_format: {
      type: "json_schema",
      json_schema: sentenceAssessmentSchema,
    },
    reasoning_effort: "low",
  });
