Xt9 repositories are empty? pkcon help

trying to find a way to see what packages a repository contains with pkcon:

a friend has a xt9-4.5 repository that contains https://store-repository.jolla.com/features/4.5.0.25/xt9/aarch64/

if i do ssu dr xt9-4.5 and i do pkcon get-packages on both, the output is the same, which would possibly mean that this repository is empty? is there a pkcon command to display all packages from a specific repository?
