Calling a function which is inside a exported function (Node.js)

In a Node/Next.js environment, I have a utility function exported like this:

export async function MyFunction(one, two, three) {
    var a, b

    // do some logic / save to context store, etc.

}

and I'm using it inside my pages/components like MyFunction("one",false,"three") , if I now have a inner function like:

export async function MyFunction(one, two, three) {
   var a, b

   function MySecondFunction(){
      a = 'a new value'
      b = 'b new value'
      // update some context stores
   }

   // do some logic / save to context store, etc.

   if(...){
      MySecondFunction()
   }

}

how can I run MySecondFunction() from outside (from my pages/components)? I found some examples but it all imply to return, the difference is here I don't have to return anything from either MyFunction or MySecondFunction

EDIT: to give more context, MySecondFunction() is a sort of "reset" of all the stores and variables set within MyFunction(). As a store management library I'm using Zustand, and I'm loading various stores, so I was wondering if I can call this "reset" (MySecondFunction) from the outside without having to require all the stores again in each component from which I'm willing to do the reset.

You can also return the second function.

export async MyFunction(one, two, three) {
  // do some logic

  function MySecondFunction(four, five, six) {
    // do more logic
  }
  
  // execute the second function from inside MyFunction (can be omitted)
  // MySecondFunction()

  // return the second function to be able to run it at a later time from outside.
  return MySecondFunction
}

//call just the first function
MyFunction("one", "two", "three");

//run the second function right after the first function
MyFunction("one", "two", "three")("four", "five", "six");

// if you want to execute the second function at a later time, you can execute MyFunction 
// and assign its return value (which is MySecundFunction) to a variable and execute it later.
let mySecondFunction = MyFunction("one", "two", "three");
mySecondFunction("four", "five", "six");

I hope this is what you mean.
