Hi! I'm setting up a Wix form where users should be able to upload their own files. The upload button already integrated in Wix forms work great, but is limited to only images and documents. I need to be able to upload mp3 files, is there a way to customize the button to do that? If not, does anyone have any tips on where to start to create such a button from scratch?
I see that other form builders (like Magic forms) have the ability to upload any file type, but these are often very limited if you don't upgrade to their premium apps.
