External Bitrise stage not showing in GitLab CI

Hello. When I push changes to my git branches on GitLab, a pipeline is kicked off successfully in Bitrise. This runs tests, lint checks etc. How do I get this to show as Stage: external like it does in these screenshots? Clicking on the text ci/bitrise/abc123xy… should bring you to the build in Bitrise. I can’t find any info on this issue so I’m assuming this stage should show automatically? Any help appreciated. Thanks.
