Limit R2 Credentials to ony one bucket

Hi, when I create new R2 API token they are working for all buckets in my account. I only can restrict them by time and IP. But I want them to be valid for just one bucket.

But there is a small hint that says: " Permissions can be further customized or created for multiple accounts from your Profile."

Following that link I can’t create R2 token.

Is it possible to create R2 token just for one bucket? I would like the know how.
