Availability of Forticlient on Linux.

[Feature Request]

I was thinking of updating the Forticlient package in the AUR (Arch user repository), from v4.4 to the current version, 6.0.

However, for that, I would require the Source Code of Forticlient, and then create the package. Is there any other way to make a package for the AUR? Or a way, where Fortinet releases an Open Source version of Forticlient, which can be used for any OS?
