I’m working on a web application where users select files in the frontend, and these files are fetched from the backend. After the selection, I want to open the user’s local Outlook client with a pre-drafted email that includes the selected attachments. The email should be ready for the user to review and send manually.

Scenario:

A user selects files in the frontend.
After clicking the “Send Mail” button, the local Outlook client should open with the files (fetched from the backend) already attached.

Requirements:

The user’s local Outlook client should open before the email is sent, not programmatically.
The files must be fetched from the backend dynamically based on the user’s selection in the frontend.
