title: How to call a Cloud Function for Firebase in Vue3
body: <p>I'm following the Net Ninja's tutorial about firebase cloud functions and I can't figure out how to call a function from a vue component. (he doesn't use vue in the tutorial).</p>
  <p>So I have this vue3 app with firebase functions installed in it. How do I import the functions into a component? I can't find the answer anywhere. I'm still learning to code and I still don't understand very well how to import the packages needed.</p>
  <p>I have a index.js file in the functions folder with a few functions inside.
  I now want to call one of them ( a .onCall function) when clicking a button in a component.</p>
  <p>I understand I need to import something in that component but I can't figure out what!</p>
