TypeScript / Cypress global Enum without import

Question

I use Cypress with custom commands and test cases.

I want to define some global enums in a file, e. g.:

enum MyEnum{
    A = "hello",
    B = "goodbye"
}

Now I want to use this enum in every file without import like this:

Cypress.Commands.add('testCommand', () =>
{
   let myEnum = MyEnum.A;
})

or:

describe("example", () =>
{  
    it("example", () =>
    {
        let myEnum = MyEnum.A;
    });
});

Is this possible?
