invoke intellisense manually or not inside class definition

[GiorgosK]

It works great inside class="..." but I can't make it work inside twig but not when its NOT associated with class="..."

For example I have code adding classes conditionally in twig file

{%
  set classes = [
    'bg-red-500 p-20',
  ]
%}

but it does not autocomplete inside the single or double quotes
is there any workaround or a way to invoke this manually ?
