Loading files (such as css) when app is being deployed - Error file not found

Hey

I’m deploying an app that has a specific github folder structure to the project at hand. In this case, I also have a css folder and I need to access the css file inside this folder. The github path would then be something like:

frontend/css/style.css

And I was trying to it like this:

from load_css import local_css
local_css(r".\frontend\css\style.css")

I keep getting file not found error. This should work, no? Does streamlit keep the folder structure from the github repo? How can I access files inside a given folder then?

As an overview, the folder structure looks like this (not all folders are here):
