How to preserve auto-completion and avoid namespace in TypeScript Files which exports functions

Question

I'm currently working on a project where I have a lot of files like that, exporting functions like this:

// file: myFunctions.ts

// Function 1
export function add(a: number, b: number): number {
    return a + b;
}

// Function 2
export function subtract(a: number, b: number): number {
    return a - b;
}

// Function 3
export function multiply(a: number, b: number): number {
    return a * b;
}

Then other files import them like this: import * as CalcFunctions from './myFunctions';

However, I'd like to organize my code in a way that allows for automatic completion and avoids changing the import names. I'm thinking of using a namespace like this:

namespace CalcFunctions
{
export function add(a: number, b: number): number {
    return a + b;
}

// Function 2
export function subtract(a: number, b: number): number {
    return a - b;
}

// Function 3
export function multiply(a: number, b: number): number {
    return a * b;
}
}

But namespace is not recommended by Eslint: https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-namespace.md

So what is the best way to manage that?
