Twig - accessing node properties How can I access node property which name starts with # in twig template?

I have content type with field Category and I need to access value of that field inside of twig template?

Using dump(content.field_category[0]) I get this

array (size=5)
  '#type' =&gt; string 'link' (length=4)
  '#title' =&gt; string 'Example' (length=5)


How to access #title ?

Thank you.
You can add this line, {{ content.field_category[0]['#title'] }} to get  value of title inside twig.
