How to remove the section numbers while colouring the whole section line using \colorbox?

Question

I have used the following piece of code for colouring the text written in the section. The only problem which I am facing is that after adding this code my section is getting numbered which I don't want. Any suggestions?

\documentclass[a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[margin=0.4in]{geometry}
\usepackage{titling}
\usepackage{titlesec}
\usepackage{xcolor,lipsum}
\usepackage[most]{tcolorbox}

\titleformat{name=\section}[block]
{\sffamily\large}
{}
{0pt}
{\colorsection}


\newcommand{\colorsection}[1]{%
\colorbox{blue!20}{\parbox{\dimexpr\textwidth-2\fboxsep}{\thesection\ #1}}}

\begin{document}

   \section{This is the title}

\end{document}

Answer 1

You're adding the section number with \thesection.

\newcommand{\colorsection}[1]{%
  \colorbox{blue!20}{%
    \parbox{\dimexpr\textwidth-2\fboxsep}{#1}%
  }%
}
