How to enable Go To Definition for dependency modules?

I use ElixirLS extension in vscode on Ubuntu 18.04. For now, Go To Definition by ElixirLS works well on non-dependency modules. I was wondering if there is any way to enable Go To Definition for dependency modules. For example this code,

defmodule Bud.Repo.Migrations.CreateUsers do
  use Ecto.Migration # <- Go To Definition here

  def change do
    create table(:users) do
      add :name, :string
    end
  end
end

I’m hoping by pressing F12(Go To Definition) on Ecto.Migration will be redirected to file deps/ecto_sql/lib/ecto/migration.ex. Is there any way to enable this kind of feature?

I think it will be quite helpful to take a look at source code directly like I used to do on PHP project with composer instead of relying on documentation only.
