Thank you, it’s a great help.It‘s not that easy.
You need to know the information (type, server, description, remote ID, password, username, ...) that‘s used to set up a VPN (company, VPN service). If you have all the information, you can set up a VPN manually, without app.

Glad to help.Thank you, it’s a great help.
