O que e como defino meu título para subir no tcolorbox?

Question

Esta é a fonte na página 182 do manual tcolorbox. Prazer em conhecê-lo. Novato em látex. É uma honra fazer-lhe a primeira pergunta.

Não sei como modificar Meu título para subir:

%------------------------
\newtcolorbox{mybox}[2][]{skin=enhancedlast jigsaw,interior hidden,
boxsep=0pt,top=0pt,colframe=red,coltitle=red!50!black,
fonttitle=\bfseries\sffamily,
attach boxed title to bottom center,
boxed title style={empty,boxrule=0.5mm},
varwidth boxed title=0.5\linewidth,
underlay boxed title={

\path[draw=red,top color=white,bottom color=red!50!white,line width=0.5mm]

Da próxima vez, forneça um documento compilado\documentclass --> \end{document}

Foi necessário mudar

• enhancedlast jigsawparaenhancedlast jigsaw
• northparasouth
• yshiftinvertido

O código

\documentclass[border=3mm]{standalone}
\usepackage[most]{tcolorbox}
\usepackage{varwidth}
\usepackage{lipsum}
