Citations not Showing up with Texstudio

Question

Sorry for the newbie question, but I have been trying to resolve the problem of citations not showing up with texstudio. Below is a sample of my tex code

\documentclass[12pt,a4paper]{article}
\usepackage{graphicx}
\usepackage[margin=1in]{geometry}
\usepackage[table,xcdraw]{xcolor}
\usepackage{float}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{chemfig}
\usepackage[backend=biber,style=mla]{biblatex}
\restylefloat{table}
\bibliography{EnzymeLabCitation}
%opening
\title{Sample Title}
\author{Me}
\date{}
\begin{document}
    This is an example sentence with citation \cite{Polysaccharides}
    \printbibliography
\end{document}

with the following in the file EnzymeLabCitation.bib

@misc{Polysaccharides,
month = {mar},
title = {{Polysaccharides}},

abstract = {Advanced stages of chronic pancreatitis and pancreatic cancers (PCs) are very serious diseases with very poor prognosis. Therefore, identification of reliable and specific biomarker(s) at early stages of the diseases could be key to their early prevention and therapy. In this chapter, currently used and putative biomarkers of acute and chronic pancreatitis and PC are summarized. Total serum lipase and/or amylase are most widely used biomarkers of acute pancreatitis; lipase assay being more sensitive and specific than that of amylase. Imaging technologies provide key support for the diagnosis of both acute and chronic pancreatitis. Biomarkers of chronic pancreatitis are poorly developed and remain challenging because of impaired secretory components of exocrine pancreas. The focus of future clinical diagnosis of chronic pancreatitis and PC lies in identification of biomarkers using omics and microRNA arrays along with imaging technologies in well-defined experimental models and their validation in patients diagnosed with various stages of chronic pancreatitis and PC.},

}

With this, the document simply shows the word Polysaccharides instead of the citation, and the title 'Works Cited' does show up, but not the sources. I have been trying to run it in overleaf, and no luck either. I am quite confused and would appreciate all help (I am using Texstudio as the main text editor).
