Upload application to hosting

[apenaranda]

Hello,
I'm testing locally with Modern-React-For-PowerBI
App for embedded power bi that is made in node.js
It works apparently fine except some export works but all ok.
Now I would like to test uploading the app to a hosting.
Could you help me how do I upload the application?
I am not very sure what files and how I have to upload, what file starts the app since the hosting asks me to do so. I attach an image of the file tree.

Thank you.

I update the error that I get

It doesn't help me much, the truth is that the app is already made, I can reproduce it locally without problems but when it comes to uploading it to a hosting, that's where it gives me problems, I don't really know how to upload it and what file activates the app .
