References and bibliography written as footnotes

Question

I have checked all the previous questions about this subject, but I have not been able to find a simple solution. I want to write the citations as footnotes, with a simple numerical index to indicate the reference. Moreover, if I cite several references in one point, I do not want a single index and in the footnote a list of references. I want a single number for each reference, and if I cite the same reference twice in the text, in two different points, I do not want to print it again in the footnote, with a new number. I don't know if I have explained myself. I want exactly the same result that I obtain with

\usepackage[super]{cite}
\begin{document}
...
\bibliographystyle{unsrt}
\bibliography{bibliography.bib}
\end{document}

but with the references written as footnotes. As an example

\documentclass[a4paper,12pt]{article}


\usepackage{filecontents}

\begin{filecontents}{test.bib}
    @book{Foo,
        title={Book title1},
        author={Author1},
        year= {Year1},
    }
@article {Bar,
    author = { Author2 and others},
    journal = {Journal2},
    volume = {2},
    pages = {022},
    year = {2022}
    }
@article {Baz,
    author = { Author3 and others},
    journal = {Journal3},
    volume = {3},
    pages = {033},
    year = {2033}
    }    

\end{filecontents}

\usepackage[style=verbose,autocite=footnote]{biblatex}
\addbibresource{test.bib}

\begin{document}
\null\vfill\noindent% just for the example
Here I want three different citation numbers (i.e. 1-3)\autocite{Foo,Bar,Baz}.\\ 
Recurrent citation, I want just the index already used (i.e. 3), no reference in the footnote\autocite{Baz}.
\end{document}

It seems that the answer here

Repeat the same reference in footnote on different pages

should solve the problem, but I am not able to make it work.

Answer 1

It seems I have found a solution here:

https://www.texdev.net/2010/03/08/biblatex-numbered-citations-as-footnotes/

Here it is:

\documentclass[a4paper,12pt]{article}

\usepackage{filecontents}

\begin{filecontents}{test.bib}
    @book{Foo,
        title={Book title1},
        author={Author1},
        year= {Year1},
    }
@article {Bar,
    author = { Author2 and others},
    journal = {Journal2},
    volume = {2},
    pages = {022},
    year = {2022}
    }
@article {Baz,
    author = { Author3 and others},
    journal = {Journal3},
    volume = {3},
    pages = {033},
    year = {2033}
    }    

\end{filecontents}
