Hi! I'm VTEX IO CI/CD Bot and I'll be helping you to publish your app! 🤖

Please select which version do you want to release:

• [x] Patch (backwards-compatible bug fixes)

• [ ] Minor (backwards-compatible functionality)

• [ ] Major (incompatible API changes)

And then you just need to merge your PR when you are ready! There is no need to create a release commit/tag.

• [ ] No thanks, I would rather do it manually 😞
