Combine all TypeScript enums into a single one

Looking for a way to combine two separate enums into one for easier use.

export enum ActionTypes1 {
  ClearError = 'CLEAR_ERROR',
  PrependError = 'PREPEND_ERROR',
}

export enum ActionTypes2 {
  IncrementCounter = 'INCREMENT_COUNTER',
}

Is there a method to access data from both enums using a single call?

For example:

Foo.ClearError // should work
Foo.IncrementCounter // should work

I am utilizing the enum for function names. When trying to replace the enum with a constant, an error occurs:

// Error: A computed property name in a type literal must refer to an expression whose type is a literal type or a 'unique symbol' type.

async [ActionTypes.IncrementCounter]({ commit }) {

If you want to achieve the same result, you can create a constant object like this:

const MyObject = {
  ...Data1,
  ...Data2
} as const;
type MyType = Data1 | Data2

const item: Data1 = MyObject.Item1;
const element: MyType = Data2.Element2;
