which ueransim is the network slicing example using

Hi all,

Thanks for maintaining this awesome project. I have the following question:

in the docker-compose/docker-compose-slicing-ransim.yaml, the ueransim image is defined as ueransim:latest. but when I pull it, it prints the error: pull access denied for ueransim.

when I searched docker hub, there are many ueransim images:

I wonder which one is it that's used in the tutorial.
