We have bought extended licenses for premium plugins that come with our theme, so you can use them for free, and we can’t give you the license codes because of policy and terms of Theme Forest.
This only means that you can not update the plugins automatically, and you need to wait for the update which will be included in latest theme updates, as soon as the new version of plugins becomes available.
You can read more about bundled plugins in the following Envato article https://help.market.envato.com/hc/en-us/articles/213762463-Bundled-Plugins
