How do I elevate a PowerShell script when run from Go?

Question

I am trying to execute a .ps1 script that I made from GoLang. In order for the script to work I need to change the execution policy to Unrestricted. In order to set that I need PowerShell admin rights.

Below is my code:

package main

import (
    "fmt"
    "log"
    "os"
    "os/exec"
)

func main() {
    app := "powershell.exe"
    restrict := "powershell start-process powershell -verb runas"
    path, err := os.Getwd()
    if err != nil {
        log.Println(err)
    }
    path = path + `\script\vpn.ps1`
    fmt.Println(path)
    restriction := "Set-ExecutionPolicy -ExecutionPolicy Unrestricted"
    confirmRestriction := "Get-ExecutionPolicy"

    power := exec.Command(restrict, restriction)
    std, err := power.Output()
    if err != nil {
        fmt.Println(err.Error())
        return
    }
    fmt.Println(string(std))

    verify := exec.Command(restrict, confirmRestriction)
    ver, err := verify.Output()
    if err != nil {
        fmt.Println(err.Error())
        return
    }
    fmt.Println(string(ver))

    fmt.Println(string(std))
    fmt.Println("ELEVATED: Set Execution Policy to Unrestricted")

    arg0 := "-file"
    cmd := exec.Command(app, arg0, path)
    stdout, err := cmd.Output()
    fmt.Println("Connecting to VPN")

    if err != nil {
        fmt.Println(err.Error())
        return
    }

    // Print the output
    fmt.Println(string(stdout))
}

Whenever I run this it fails and when I try the PowerShell command (powershell start-process powershell -verb runas) directly at the command prompt I get this error:

-verb : The term '-verb' is not recognized as the name of a cmdlet, function, script file, or operable program. Check
the spelling of the name, or if a path was included, verify that the path is correct and try again.
