how to store and download external pdf in odoo 14

My project involves implementing a feature to download external PDFs in Odoo 14. This can be achieved through the use of Python programming language. The goal is to create a web interface with Odoo to store the PDFs. This will involve designing a feature that can allow users to download the PDFs, and developing an automated system for data handling. Furthermore, the PDFs will be stored in a database. This project requires a high level of expertise in Python and Odoo, and experience with data handling in order to complete the project successfully.
