How to add a custom property to an existing Go structure?

Question

go

Greetings!
I get a TCP connection with the following code:

ln, err := net.Listen("tcp", Server.GetHost()+Server.getPortForNet())

for {
    connection, err := ln.Accept()
}

connection - net.Conn interface .
I need to add some custom properties and methods to this structure.
For example:

?{
name string
lastname string
}

func (Connection *?) GetName() string {
    return ?.name
}

func (Connection *?) GetLastName() string {
    return ?.lastname
}

Those. I will have to be able to write something like this:
connection.getName()
How to do it right? Thanks for the help.

Why don't you just want to create a structure like this?

struct User {
    Name string
    LastName string
    Connection net.Conn
}
