Remote Registry Browser with private registry

How can one point the Docker-Desktop UI registry browser to a private registry ?

Right now it requires to login into hub.docker.com, and it pulls registries online. We have a private registry that I’d like to integrate into Docker Desktop

You can’t do that. The Docker Desktop UI supports only Docker Hub, but you can use the docker command from the terminal to login to the registry and pull images from it. After that you can find the pulled image on Docker Desktop UI
