looks good 🎉

@joshblack I have a quick follow-up question: Do the framework-specific icon packages (@carbon/icons-react, @carbon/icons-vue, @carbon/icons-angular) get updated automagically or do I need to submit a PR for them as well?

Also, how can I contribute them to the master sketch libraries? (https://www.carbondesignsystem.com/resources#color-grid-and-icons)

[joshblack]

@janhassel they should get updated automatically! If not, it definitely is an issue and let me know 😅 Should be in our next release! The same would go for our sketch library for icons as that is generated from code, as well 👍

[laurenmrice]

^For our next release we will need a dev resource so we can get the new icons into the plugin so we can update the libraries.

@laurenmrice made a quick issue for this over in: #4849 for us

@joshblack Awesome, sounds good. Thanks for the info!
