Seed associative entities using nestJS + typeORM + nestjs-seeder

Do you know how can i seed random associative entities with using nestJS + typeORM + nestjs-seeder I only know how to use static element

@Factory('static_var')

or faker

@Factory(faker => faker.name.findName())

or custom functions

@Factory(() => {
  const minAge = 18;
  const maxAge = 30;
  return Math.round(Math.random() * (maxAge - minAge) + minAge);
})

But i want to be able to insert random Ids from an associative table
