What happens next?

Thanks for the contribution! We try to make sure all PRs are reviewed ahead of a monthly dev call (first Monday of the month, open to all!).

If the PR is working as intended it'll be merged and included in the next platform release, if not changes will be requested and re-reviewed once updated.

If you need more immediate feedback you can try reaching out on slack in the platform-dev channel.
