I would like to embed helm inside a cli program that I'm writing
many cli programs, specially ones written using cobra, allow me to do that like this:

package tools

import (
	k3d "github.com/k3d-io/k3d/v5/cmd"
	"github.com/spf13/cobra"
	kubectl "k8s.io/kubectl/pkg/cmd"
)

var ToolsCmd = &cobra.Command{
	Use:   "tools",
}

func init() {
	ToolsCmd.AddCommand(k3d.NewCmdK3d())
	ToolsCmd.AddCommand(kubectl.NewDefaultKubectlCommand())
	RootCommand.AddCommand(ToolsCmd)
}

When I try to do the same for helm I get the flowing error:

import "helm.sh/helm/v3/cmd/helm" is a program, not an importable package

In order to support this for helm, the main file (named helm.go in this case) needs to be separated from the rest of the code.
