Given the many-to-many relation example given in the docs with User and Car in a many-to-many relationship, how does one associate an existing user to an existing car using FQL? Can Connect be used? Does the related index have to be updated directly (e.g. user_cars_by_user, user_cars_by_user_and_car, user_cars_by_car)? Can someone give an example of associating an existing User to an existing Car using FQL for the schema below? Thanks for any help!
type User {
name: String!
drives: [Car!] @relation
}
type Car {
plate: String!
drivers: [User!] @relation
}
