Outer function argument not displayed when debugging inner function in chrome

Question

I have function like:

const outer = payload => dispatch => {
   debugger;
return 0;
}

Should I see payload variable when debugging it in chrome devtools? I was looking for it in closures as you can see in the screenshot. There is no payload there or I cannot find it. However when I change the code to:

const outer = payload => dispatch => {
   console.log({ payload });
   debugger;
return 0;
}

I can see payload variable appearing under one of the closure boxes on the right side when debugging.

I think I don't fully understand the behaviour of closures(?) Could you please tell me in short how these two codes work behind the scenes?
