Add subcommand in go cobra with multiple parents

I want to have the option of the following cmd invocations in a cli tool I am building in go using cobra:

$ mytool envs apps compare
$ mytool envs vars compare

So am creating the commands and performing the bindings as follows:

    rootCmd.AddCommand(envsCmd)
    envsCmd.AddCommand(appsCmd)
    envsCmd.AddCommand(varsCmd)
    varsCmd.AddCommand(compareCmd)
    appsCmd.AddCommand(compareCmd)

However, when checking the parent of the compare subcommand, it always turns out to be apps

var compareCmd = &cobra.Command{
    Hidden: false,
    Use:    "compare",
    Short:  "",
    Long: ``,
    RunE: func(cmd *cobra.Command, args []string) error {
        fmt.Println(cmd.Parent().Use)

The above always prints apps no matter if I invoke

$ mytool envs apps compare

or

$ mytool envs vars compare

Should I assume what I want to achieve is not possible at least using cobra?

The commands are linked using pointers, so the last one you add becomes the parent command. Try two copies of the same command instead:

var baseCompareCmd = cobra.Command{...}
var varCompareCmd = baseCompareCmd
var appsCompareCmd = baseCompareCmd

varsCmd.AddCommand(&varCompareCmd)
appsCmd.AddCommand(&appsCompareCmd)
