I have the following code:
\documentclass[11pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage[citestyle=bwl-fu, maxcitenames=3, maxbibnames=20, firstinits=true]{biblatex}
\addbibresource{literature.bib}
\renewcommand{\mkbibnamefamily}[1]{\textsc{#1}} % Authors in small caps in citation and bibliography
\DeclareNameAlias{default}{last-first} % family name, given name
\renewcommand*{\multinamedelim}{\addsemicolon\space} % semicolon between two authors
\DeclareFieldFormat{labelnumberwidth}{Test} % print nothing in the label
\DeclareCiteCommand{\cite} % hyperlink authoryear to bibliography
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\printtext[bibhyperref]{\usebibmacro{cite}}}
{\multicitedelim}
{\usebibmacro{postnote}}
\usepackage{hyperref}
\begin{filecontents}{literature.bib}
@article{Mueller.2018,

@book{Junker.2008,

}
\end{filecontents}
\begin{document}
\chapter{Test-Kapitel}
\cite{Mueller.2018} haben eine Meinung. Aber \cite{Junker.2008} sehen das anders.
\printbibliography[title=Literaturverzeichnis]
\end{document}
But instead of "Test" in the bibliography I need author (year) as a reference. I'd like to have something like:
