Change license on website to new theme purchase

Hello! We have a website currently running the Enfold theme under a license purchased by our developers. We have gone ahead and purchased our own version of the theme so we have access to future updates. I am hoping someone can advise me on how to re-configure our theme config file settings to add our new license in? I can’t seem to find any documentation on how to do this and themeforest support has advised this is the next step.

Thank you so much for any help!
