This will provide you with a sandboxed VM, but that VM is an entire OS, not simply an app with limited access.

While there are attempts to try and keep Flatpak applications secure, most applications have filesystem=host, filesystem=home or device=all permissions, which allows the application to write to the disk anyway, meaning that one malicious update to an application can lead to a major security issue.
