I'm utilizing the Mailchimp extension in firebase with regular firebase auth, but as I use custom claims to differentiate between people currently subscribed and those who have made an account but aren't currently subscribed, the sample code that firebase provides does not work as it's made for firestore (the following)
{
"memberTags": ["domainKnowledge", "jobTitle"],
"subscriberEmail": "emailAddress"
}
Is there a way to automatically tag with a custom claim or does that have to be coded separately (or is mailchimp just not the best tool in general for this)?
