• High risk changes are those that could impact customers and SLOs, low or no test coverage, low observability, or slow to rollback.

What approach did you choose and why?

I added a new parameter, inactive, that sets a button to aria-disabled. I chose this approach to align with the PRC API (PR: primer/react#3812)

Uh oh! @mperrotti, the image you shared is missing helpful alt text. Check your pull request body.

Alt text is an invisible description that helps screen readers describe images to blind or low-vision users. If you are using markdown to display images, add your alt text inside the brackets of the markdown image.

Learn more about alt text at Basic writing and formatting syntax: images on GitHub Docs.
