How to execute toast actions using buttons in go

[blyat_lasagna]

This code from the https://github.com/go-toast/toast package of GO below opens up map. How do I open terminal using that action button to execute a command?

package main
import (
    "gopkg.in/toast.v1"
    "log"
)

func main()  {
    mivo()
}


func mivo()  {
    notification := toast.Notification{
        AppID: "Mivo",
        Title: "Break, boss",
        Message: "30 minutes passed! You are to go for a walk now.",
        Actions: []toast.Action{
            {"protocol", "Alright", "bingmaps:?=sushi"},
            {"protocol", "GG", ""},
        },
    }
    err := notification.Push()
    if err != nil {
        log.Fatalln(err)
    }
}
