Tcolorbox – How to Remove White Space on a Box Using Tcolorbox

Question

I'm trying to make a box with the same size as the writing, but i don't know how. My code:

\documentclass[A4paper, twoside, 11pt]{article}
\usepackage[top=2.5 cm, bottom=3.8 cm, left=2 cm, right=2 cm]{geometry}
\usepackage[most]{tcolorbox}
\tcbuselibrary{skins}
\usepackage{hyperref}
\hypersetup{colorlinks=true,
    linkcolor=blue,             
    urlcolor=blue,
    citecolor=cyan}
\urlstyle{same}

And i obtain this result:

But i want something like that:

By default, a tcolorbox uses \linewidth as initial size. To my knowledge is not possible to automatically adjust the width to the contents, but you can use width and text width options to reduce box width.

Following code shows the result with text width. In this case a new tcolorbox called mybox is declared. This reduces typing. The new tcolorbox has one mandatory parameter, the title, and an optional one. In the example this optional parameter is used to introduce any change to the default maybox, like text width.
