Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

• Make sure to open a GitHub issue as a bug/feature request before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
• Edit the title of this pull request with a semantic commit prefix (e.g. "fix: "), which is necessary for automated release workflows to decide whether to generate a new release and what type it should be.
• Will this cause breaking changes to existing Java or Kotlin integrations? If so, ensure the commit has a BREAKING CHANGE footer so when this change is integrated a major version update is triggered. See: https://www.conventionalcommits.org/en/v1.0.0/
• Ensure the tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (if necessary)
