Get a PDF file saved on mobile and store in Firebase

In my services app, when a professional downloads a pdf and saves it in a specific location such as the download folder, I want to get this file and store it in firebase storage so that any client of mine can view it later. Is it possible to do this?

How u can save ? There is no option to save anything in firebase
Just see IN UI ( User Interface ) Media_DB You can save there by using
And if u want more information about cloudinary go to thunkable docs and just take a look
