Do Workers now have a preview environment?

Since pages is moving to workers, does that mean we can manage multiple workers environments (with variables/secrets) for both dev and prod projects like how pages exists now? I dont see this toggle in existing workers dashboard. But i do see preview urls (but im assuming thats just urls). https://developers.cloudflare.com/workers/configuration/previews/

Preview URLs

Preview URLs allow you to preview new versions of your project without deploying it to production.
