  @timofurrer I started working on your edits yesterday, but ran into a problem. To do the real revisions I want to do, I need to use backticks in the display text. How should I do that inside this heredoc string?

  Let me know, and I can polish your text + publish it when I'm back from leave. (My coverage issue: https://gitlab.com/gitlab-org/technical-writing/team-tasks/-/issues/1374) I've approved, so you can move forward without me - make a follow-up issue for me and I will edit the strings when I return.
