If I integrate the Google People API into my Chrome extension, do the “per user” write requests refer to each individual user of the extension or to my Google Cloud Console account?

For example, does “30 write requests per minute per user” mean that each individual user of my Chrome extension has 30 write requests per minute, or does it mean that the extension can only send a total of 30 write requests to the API per minute?

Thank you for your help 🙂

Before I proceed with the API integration, I would like to clarify this question.
