@goveo Any chance you could take a look at this PR? Or is there a different approach that is already available that has this same functionality?

I want to add this functionality to be able to override fields/html attributes on the button element such as aria-label, id, etc..

Thanks for the contribution!!
Overall it looks good, but docs updates are missing.

Please add new props to the docs.
Also remove pnpm-lock.yaml change please 🙏

@goveo - sorry for the delay. updated to include docs change. I can't seem to remove the pnpm-lock.yaml file changes, I believe its just whitespace changes... can we merge this anyways?
