Custom domain name to serve Python packages from Google Artifact Registry?

[paolofilippelli]

we're serving Python packages through Google's Artifact Registry. Actually the URL is the "default" one, so

https://[REGION].pkg.dev/[PROJECT_ID]/.....

but what if we wanted to use a custom domain name? For example we'd like to serve packages from a custom domain link like

https://[MY-CUSTOM-DOMAIN]/...

Is there an official way to do that? What are my options?
