I would like the mailchimp extension in firebase to sent the field displayName to mailchimp as firstName (or as a custom field, I dont mind either way. I used https://extensions.dev/extensions/mailchimp/mailchimp-firebase-sync and put in Firebase Member Tags Config the following:
json { "memberTags": ["displayName"], "firstName": "displayName" }
Which did not work. How do I fix this?
