Docker container images required to install GitLab CE offline with Helm

Hi, I’m trying to install GitLab CE v13.9.1 using Helm chart v4.9.1.

However, I’m doing this in an air-gapped environment with only a private docker registry using Nexus3.
My k3s is configured to pull images from this registry already and it works but I need to upload the images required for GitLab CE both image name and tag and I cannot find that list anywhere.

The default values.yml in the chart even says the following:

## NOTICE
# Due to the scope and complexity of this chart, all possible values are
# not documented in this file. Extensive documentation for these values
# and more can be found at https://gitlab.com/gitlab-org/charts/gitlab/ 

However the chart documentation most of the time has the tag master or an empty tag for the image.

My question is, is there such a list? containing all the images that GitLab helm chart will use to configure GitLab?

Thanks a lot!!!
