add sub section with no used references in the reference section R Markdown

Question

I have created my thesis with R markdown and in the project created ( Database application) I have used 48 papers that I have to add the to references, I didnt mention them in the thesis I have just to add a sub title in the references called : Used in the application and put them all. my references list is created with bibtex

Is there a solution to import my references list with a subltitle in he references section knowing that I have other references That I already put in the references

My desired output may be like this

 References
   1 abcd
   2 efjh 
Used in the application
    1 xyz
    2tuv

You can use the multibib package to achieve this:

---
output: 
  pdf_document:
    citation_package: natbib
header-includes:  
  - \usepackage{multibib}
  - \newcites{App}{Used in the application}
---

\bibliography{bibliography}


\nociteApp{*}
\bibliographyApp{library}

Result using two bib files I had available:

Note that by not including bibliography in the YAML header I am tricking the system into not including the default reference section after the body. This gives me the freedom to include my own reference sections. One with my normal references from the bibliography.bib and one section from library.bib. Via \nociteApp{*} I am citing all of them without leaving any mark in the text.
