For Google Cloud's debian repository, which distribution corresponds to Debian Testing (currently, Trixie)?

On Debian Testing (currently called Trixie), I would like to install the google-cloud-cli and google-cloud-sdk-gke-gcloud-auth-plugin packages that Google Cloud offers through its debian (package archive) repository packages.cloud.google.com/apt/ . But **which *(package archive) distribution* is the correct one to use?** In their official documentation, Google Cloud instructs to use the cloud-sdk distribution, regardless of the Debian version that it is running:

deb [signed-by=/usr/share/keyrings/cloud.google.gpg] http://packages.cloud.google.com/apt  cloud-sdk main

But I'm hesitating to just use it because when we take a look at packages.cloud.google.com/apt/dists , we can see a long list of distributions that are specific to Debian versions. There is even a distribution specific to unstable/sid; but there is no distribution specific to testing/trixie:

cloud-sdk
cloud-sdk-artful
cloud-sdk-artful-unstable
cloud-sdk-bionic
cloud-sdk-bionic-unstable
cloud-sdk-bookworm
cloud-sdk-bullseye
cloud-sdk-bullseye-unstable
cloud-sdk-buster
cloud-sdk-buster-unstable
cloud-sdk-cosmic
cloud-sdk-cosmic-unstable
cloud-sdk-disco
cloud-sdk-disco-unstable
cloud-sdk-internal-testing
cloud-sdk-internal-testing-unstable
cloud-sdk-jessie
cloud-sdk-jessie-unstable
cloud-sdk-precise
cloud-sdk-precise-unstable
cloud-sdk-sid
cloud-sdk-sid-unstable
cloud-sdk-stretch
cloud-sdk-stretch-unstable
cloud-sdk-trusty
cloud-sdk-trusty-unstable
cloud-sdk-unstable
cloud-sdk-utopic
cloud-sdk-utopic-unstable
cloud-sdk-vivid
cloud-sdk-vivid-unstable
cloud-sdk-wheezy
cloud-sdk-wheezy-unstable
cloud-sdk-wily
cloud-sdk-wily-unstable
cloud-sdk-xenial
cloud-sdk-xenial-unstable
cloud-sdk-yakkety
cloud-sdk-yakkety-unstable
cloud-sdk-zesty
cloud-sdk-zesty-unstable

So, given these circumstances, which distribution is the correct one to use? Also, should I report a bug to Google Cloud?
