Hi,
You only need 1 EC2 instance as a network connector that will act as Internet Egress.
Also, please do not use the connection profile (.ovpn file) of your connector for your client. A connection profile cannot be used simultaneously on multiple devices. It can only be used on one device. If another device is using it, the first will be disconnected.
For the user/client profile, you must create a user and must follow the below link to download the OpenVPN Connect app, retrieve an OpenVPN profile, and connect to the VPN:

For the VPN egress, please follow the below guide:

If you have some doubts, you can open a ticket at
