Need help uploading to sharepoint

Hi Annika if you don't get a quick answer from this forum, I would recommend trying a SharePoint forum and asking the question "how do I publish a website on sharepoint". If you publish the Storyline module to Web, it produces a number of assets including HTML, JS, CSS and images etc. You need all of these files for the resource to work correctly. The initial file (launch file) is named "story.html".

You might even find a solution using a service like ChatGPT and asking the same question. 

Also, I'd recommend a search through these forums too if not already done, as I see SharePoint crop up a lot in discussion.
