Linking to source code on GitLab?

I’ve enabled the GitLab integration for my my project, but there doesn’t seem to be a way, to establish how build machine source paths map to paths on the GitLab repositories? I was hoping I could click a link in a back-trace and jump to the code on GitLab.

I have added the repositories in the ‘repositories’ section of my project settings, of course.

The stack-trace path is something like: C:\Jenkins\workspace\myproject\git-repo\foobar.cpp and the path on GitLab is something like
https://gitlab.com/mygroup/myproject-git-repo/-/blob/next/foobar.cpp

This is all with the Native SDK and C++ code, in case it’s relevant. PDBs for the exe are uploaded fine.
