Clients in VPN - OpenVPN - Clients - are for VPN services like SurfShark, NordVPN. ExpressVPN.. where the connections you create to these services would show as clients. I think you are running your own OpenVPN server for "Road Warrior" access. So no, if I am correct in my perspective.
However if you want to assign a specific IP to each "Road Warrior" device you can us the "Client Specific Overrides" - VPN - OpenVPN - Client Specific Overrides.
