Installing Kali Linux in Docker and accessing it's GUI over the browser

So I'm pretty new to Docker and all that stuff.I would like to install Kali Linux as a Docker container and access its GUI from the browser. How do I do that? I use Portainer as a GUI for managing Docker containers.

If possible, I'd like to have access to the Kali GUI over a domain.I'm already using nginx proxy manager in a Docker container on my machine.I also installed a desktop environment on the container, but I have no idea how to access it.

Thanks for your help in advance

PS: I'm sorry if this question is stupid, or so, as I said, I'm a newbie working with Docker and all that, so forgive me
