Which FortiClient license to buy only for VPN + tech support?

Hi,

Our company will use remote access (SSL) VPN. No any other features of FortiClient are required.
We want to avoid free 'FortiClient VPN' software because we want technical support.

However, I can only see 'VPN/ZTNA', "EPP/APT' and 'Managed'. We don't want to install any server software on our on-premise server and don't want to subscribe cloud EMS.

Does someone know which FortiClient license is suitable for our case, VPN + Tech support without any additional features? I will contact a reseller but I want to check it via different source.

Thanks.
