Hi,

​

In settings there is option to add VPN manually without app and connect does anyone know how to do this?

Some sort of client you will need, either the Proton App, an OpenVPN, WireGuard or IKEv2 app:

Honestly I‘d just get the Proton VPN app, to benefit from the advanced options you don‘t have in the manual configurations
