We tried to solve this by matching the org.fwupd.hsi AppStream ID, but in some cases the resolution depends on what actually failed. Add "the action the user is supposed to do" as flags so that the front-end can translate this in the appropriate way, for instance, using a different string for log events and HSI dialogs.
