Thank you! This looks good but can you add a changeset please?

Sorry, I don't know how to add changeset, should I run pnpm changeset and bump up @openai/agents-openai to version 0.0.4?

When you run pnpm changeset command, the interactive mode asks you to select the changed module and whether it's a major, minor, or patch version upgrade. Please select only agents-openai and choose the "patch" upgrade. There is no need to specify a specific version.

When I run pnpm changeset in GitHub workspace, it works not as expected.

It doesn't ask me to choose patch version 🥲

I do understand the interaction could be a bit confusing 😅 , but you can just hit the enter button when you’re asked about major and minor version bumps. Then, the shell will then select "patch" for you.

I just hit enter button, but it still generates major tag in changesets file. So I just changed it to patch.
