Importing MP3 Song Library from iPad to Apple Music on Windows

Recently I've been looking to import my collection of songs from my iPad to my Windows PC. Most of the songs on my iPad are .mp3 files downloaded onto my iPad from a different computer in addition to iTunes purchases.

However, whenever I connect my iPad to my Windows PC, it has only given me the option to import my library from my Windows computer (which only has iTunes purchases and no .mp3 files) to my iPad and not the other way around.

Is there a way I can set Apple Music on Windows to import my full library of songs from my iPad, including all the .mp3 files alongside the iCloud music already present?
