I was typing my Conference Paper in Overleaf (never used it before). Things were going smoothly till I reached the citations part.

main.tex

\usepackage[style=springer,doi=true,url=true]{biblatex}
\addbibresource{references.bib}
\cite{<name>}

references.bib

@inproceedings{<name>,
  author    = {},
  title     = {},
  booktitle = {},
  year      = {},
  doi       = {},
  url       = {}
}

This is how I used it, but I got an error saying:

Package biblatex Error: Command '\cite' undefined.

Attached is how the pdf was rendered PDF Rendered from code

how do i fix it so that it shows something like AuthorName, ConferenceDetails, YearOfPublication,....Link:
