Hosting Plotly Locally Coded HTML on Plotly for Powerpoint Embedding

Hello, this is my first post so I apologize if I have placed this in the wrong category!

I am looking for a way to upload my plotly chart I coded locally onto the Plotly service, so I can embed it in a powerpoint with the Plotly add-in that only allows Plotly addresses to be used. It won’t even allow me to point to a local drive location with the plotly HTML, unfortunately.

How can I get this to work?
