Use .sty in IguanaTex

How can I use a self written .sty-file in IguanaTex? Where should the file be located?

I have written a long file MyPersonalStyle.sty containing all the commands that I frequently use. I use this .sty-file` in all of my LaTeX-files. Every time I want to copy LaTeX-code from my papers to IguanaTex-Powepoint I need to redefine all these commands.

I can define a IguanaTex-template

documentclass{article}
usepackage{amsmath}
usepackage{MyPersonalStyle}
pagestyle{empty}
begin{document}




end{document}

but where do I need to put MyPersonalStyle.sty for IguanaTex to find it?
