Use this method to create an email token for a Store-specific Customer during their email verification process.
If the Customer exists in the Project but the `stores` field references a different Store, this method returns a [ResourceNotFound](ctp:api:type:ResourceNotFoundError) error.
Creating an email token for the Customer produces the [CustomerEmailTokenCreated](ctp:api:type:CustomerEmailTokenCreatedMessage) Message.
The Message will include the token's value, if the token's validity is 60 minutes or less.
