Help, how can access the web server?

I'm working on Nopcommerce V3.9 for No Source code version (using admin panel) only.

My manager do all the steps of downloading the store ang give me the link only to start working on it, now I want to add new plugin and I read that I need to access the web server that is hosting the site.


Can anyone helping me please. Thanks.

The hosting service should provide a "control panel" interface, with a "File Manager" where you can Upload the plugin/files.
(Or, you can use an FTP client like FileZilla, if you get the server FTP access info)
