How to unify messages from two different CIs?

I am running Danger from both Bitrise and from GitHub Actions. I'd like for a single message to be maintained and updated regardless of which CI ran Danger. Currently, each CI produces a unique message. I've tried using a constant id (`danger-swift ci --id "constant"`) when running Danger from both CIs, but this still doesn't fix the issue.

Does anyone have any ideas?

As an aside, I'm trying to track down where in danger-js the separate messages might be coming from, and where messages from the same CI are updated. What are the relevant pieces? I've done some digging but I haven't identified anything definitively.
