gorm postgres query json array for element

in my golang project I use postgres with gorm and I have an attributes column with the following json:

{"email": ["eee@ccc.cc", "rrr@bbb.cc", "ttt@ccc.zz"], "mail_folder": "some_folder"}
{"email": ["zzz@ccc.cc", "aaa@bbb.cc", "bbb@ccc.zz"], "mail_folder": "some_folder"}

So I need to get a record which contains email eee@ccc.cc which is the first one. I can extract it with plain sql in sql editor with the following query:

select * from authors a where attributes @> '{"email": ["eee@ccc.cc"]}';

but in gorm I keep getting wrong json syntax errors etc. I tried to do it with Raw() query or with

Where(fmt.Sprintf("attributes ->> 'email' = '[\"%v\"]'", email)).

but it did not work either. Any ideas how to fix it would be welcome. Thank you.

Sampledb in postgreSQL:

Create Table authors
(
    id         serial,
    dummy      text,
    attributes jsonb
);

insert into authors (dummy, attributes)
VALUES ('eee', '{
  "email": [
    "eee@ccc.cc",
    "rrr@bbb.cc",
    "ttt@ccc.zz"
  ],
  "mail_folder": "some_folder"
}'),
       ('zzz', '{
         "email": [
           "zzz@ccc.cc",
           "aaa@bbb.cc",
           "bbb@ccc.zz"
         ],
         "mail_folder": "some_folder"
       }');

This works fine:

package main

import (
	"fmt"
	postgres2 "github.com/jinzhu/gorm/dialects/postgres"
	"gorm.io/driver/postgres"
	"gorm.io/gorm"
	"log"
)

var (
	dsn = "host=localhost user=postgres password=secret dbname=sampledb port=5432 sslmode=disable TimeZone=europe/istanbul"
)

type Author struct {
	Id         int `gorm:"primaryKey"`
	Dummy      string
	Attributes postgres2.Jsonb `gorm:"type:jsonb;default:'{}'"`
}

var DB *gorm.DB

func main() {
	DB = initDb()
	listAuthors()
}

func listAuthors() {
	var authors []Author
	DB.Find(&authors, "attributes @> '{\"email\": [\"eee@ccc.cc\"]}'")

	for _, a := range authors {
		fmt.Printf("%d %s %s\n", a.Id, a.Dummy, a.Attributes)
	}
}

func initDb() *gorm.DB {
	db, err := gorm.Open(postgres.Open(dsn))
	if err != nil {
		log.Fatal("couldn't connect to db")
	}
	return db
}

For the sample data prints:

> 1 eee {{"email": ["eee@ccc.cc", "rrr@bbb.cc", "ttt@ccc.zz"],
> "mail_folder": "some_folder"}}
