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 it's GUI from the browser. How do I do that? I use Portainer as a GUI for managing the 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
