Somehow subscribed to unsubscribable code snippet

I’m somehow subscribed to Fastlane file structure ($1895688) · Snippets · GitLab but didn’t subscribe myself, and only contributed a comment after receiving e-mails. Another person (a respondent to the linked comment) is experiencing the same.

I don’t see any option to unsubscribe from the snippet. Is this possible? If not, I’ll use https://support.gitlab.com/hc/en-us/requests/new?ticket_form_id=334447
