Change/edit the double opt-in succes message after submitting the form

Hi!

I love the plugin, thank you for creating this and sharing it for free.
Is there an easy way to change the (green) elp_msg that the user sees after submitting his name and email, when the double opt-in option is effective. What would you advise?

I’m talking about this text:
