So this moves the pictures during the shoot automatically? How you set it up?
Yes - you can select to transfer the images immediately as you shoot, or later. Details are in the Canon 5D4 WiFi manual. You need to setup an FTP server on the destination computer, of course.
The Canon WiFi manual is incorrect in listing supported OS, because it only lists the Windows "desktop" ones on which the Microsoft FTP server can be installed. FTP is a fairly standard protocol, so I guess it will work with *any* decent FTP server on Windows, OSX/macOS, Linux, etc. etc. For example, you can install the open source Filezilla FTP server on Windows version for which MS FTP is not available, if needed.
Explaining how to configure an FTP server depends on which one, and you can easily find tutorials. Basically, you setup some folders on your systems to be accessible via the FTP protocol through the server - in this case the camera can copy the images to the destination folder.
FTP (File Transfer Protocol) was designed exactly for this task, and have some advantages over HTTP especially when used on a local network (it does work over the Internet too, but often it is blocked for security reasons, and it will need to be secured otherwise everything is transmitted in clear). And unlike Canon web support, it doesn't send your images to remote cloud services.
Once the file are on the target system, then you'll need a way to display them to your audience. To support almost any user, the simpler way is to install (or create) a small web application that displays the last image on the connected browsers - I've no suggestion here, as usual it depends on what systems you're using, and what you want to achieve.
Such a setup requires some work, if you have questions, ask
