Autocomplete for links - CodeMirror Addons

**How to implemet autocomplete using CodeMirror Addons?**

I want to implement an autocomplete feature, so when the user starts typing a link, the editor would suggest from a predefined list of options.

Exploring CodeMirror I found [this autocomplete example](https://codemirror.net/demo/complete.html) that uses addons.

I could find on the easymde docs how to add addons to the underlying CodeMirror instance. Would I have to change easymde code? If so, is it just a matter of passing the addons in the easymde options and the pass those when initializing CodeMirror?
