Dropdown with list of values in smart action form

Context: Within a smart action form, I want to enable my users to choose the value of an input field within a set of predefined values.

Here I have a smart action called change status for the collection companies. I want users to be able to only select the new status from a list of possible options.

forest/companies.js

const { collection } = require('forest-express-sequelize');

collection('companies', {
  actions: [
    {
      name: 'Change status',
      type: 'single',
      fields: [
        {
          field: 'New status',
          type: 'Enum',
          isRequired: true,
          enums: ['Pending', 'Live'],
        },
      ],
    },
  ],
  fields: [],
  segments: [],
});
