There are many questions and answers surrounding how to make the Table of Contents content clickable. I am wondering how to make a reference to the Table of Contents and create a link elsewhere in the document to click on and go back to the table of contents.
I have tried giving the Table of Contents its own label via \tableofcontents\label{toc} and then using a reference link \ref{toc} but this produces the error: ./project.tex:133: Package hyperref Warning: Suppressing empty link on input line 133.
