Upload file to Microsoft Fabric

I want to develop an app to upload a file (specifically a CSV file) to a Microsoft Fabric cloud server (I think it is called a OneLake". But I don't know how to do it. I'm searching for suggestions to it. I have these ideas:

1. A Django app and connect it to Microsoft Fabric
2. Use a PowerBI dashboard using a button and a power app or power automate; maybe use a pipeline.

The requirement is that the file be uploaded to Microsoft Fabric.

Thank you so much, and sorry for don't provide specific details, really Im a little missed up with this.

There is an official Microsoft OneLake File Explorer application that may be sufficient https://learn.microsoft.com/en-us/fabric/onelake/onelake-file-explorer.

Additionally, when uploading files to OneLake there should be a specific destination that includes a workspace and a Lakehouse. There is no direct "file storage" on OneLake. Files can only reside inside workspaces, and if they are data files then the only destination is a File section in a Lakehouse.
