How can I fix 'undefined' output from my function that retrieves cookie values in Electron using Node.js promises?

Question

I have this function to get cookies values if cookies exist or false if not, but i get undefined

This is my function :

function ifCookieExist(cookieName) {
    session.defaultSession.cookies.get({ name: cookieName })
      .then((cookies) => {
        return cookies[0].value
      }).catch((error) => {
        return false
      })
  }

called here : console.log(ifCookieExist('actualList'));

actual result : undefined expected result : cookies value or false

for info when i use console.log inside function like this :

function ifCookieExist(cookieName) {
    session.defaultSession.cookies.get({ name: cookieName })
      .then((cookies) => {
        console.log(cookies[0].value)
      }).catch((error) => {
        return false
      })
  }

i got expected result in console
