PHPStorm correct PHPDoc for a Collection of Strings

Question

I have this collection and would like to annotate the correct PHPDoc for this collection. Would it be Collection<string>?

Illuminate\Support\Collection^ {#525
  #items: array:3 [
    0 => "string_1"
    1 => "string_2"
    2 => "string_3"
  ]
  #escapeWhenCastingToString: false
}
