Switch: create all cases - doesnt work for dynamic union type

[sellalone]

Describe the bug

I have dynamic union type as type Animal = "cat" | "dog" | "rabbit" | "snake" coming from string literal type of array values and I don't see the option Create all cases

How to reproduce

try to use the following code :

export type Lit = string | number | boolean | undefined | null | void | {};
export const tuple = <T extends Lit[]>(...args: T) => args;

const animals = tuple('cat', 'dog', 'rabbit', 'snake');
type Animal = (typeof animals)[number];  // union type

function getAnimalInfo(value: Animal): string {
  switch (value) {
  }
}

Expected behavior

Successfully creates a case for each member of the union type like

function getAnimalInfo(value: Animal): string {
  switch (value) {
    case 'cat':
      return 'Here is some info';
    case 'dog':
      return 'Here is some info';
    case 'rabbit':
      return 'Here is some info';
    case 'snake':
      return 'Here is some info';
    default:
      return '';
  }
}
