How to send a folder (with files) from Bubble interface to external storage

Hi,

I have tried using Bubble like a FTP, sending a folder to other storage, but without success.

I have tried some plataforms (Firebase, Box), but with these solutions is not possible send a folder, only files.

My ideia is allow ny user upload digital publications (in HTML with others files - JS, image, css, each one inside your folder

After upload I will get the URL (from index.html) to show the publication inside bubble as an iframe

Thanks any help
