Entity Framework 6: Problem with many to many relationship

I started with a tutorial, where I created classes :

namespace SamuraiApp.Domain
{
    public class Battle
    {
        public int BattleId { get; set; }
        public string Name { get; set; }
        public List<Samurai> Samurais = new List<Samurai>();
    }
}

and

namespace SamuraiApp.Domain
{
    public class Samurai
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public List<Quote> Quotes { get; set; } = new List<Quote>();
        public List<Battle> Battles { get; set; } = new List<Battle>();
    }
}

and dbcontext

 public class SamuraiContext:DbContext
    {
        public DbSet<Samurai> Samurais { get; set; }
        public DbSet<Quote> Quotes { get; set; }
        public DbSet<Battle> Battles { get; set; }
          protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            optionsBuilder.UseSqlServer("Data Source= (localdb)\\MSSQLLocalDB; Initial Catalog=SamuraiAppData");
            // si on a sqlLite on va écrire  optionsBuilder.UseSqlLite("<chaine de connexion sqlite>")

        }

    }

I thought that entityFramework6 alone interprets the many-to-many relationships and generates the intermediate table BattleSamurai, but the generation of the base did not take into account this relationship (see screenshot).

Do you have any comments, please?

Add public int BattleId { get; set; } to Samurai and public int SamuraiId { get; set; } to Battle.

To make sure you can see in migration if Samurai has foreign key to Battle and vice versa.

I am following this article about Many-to-Many relationships in EF.

According to it, the code should look like this (Please note that I can't see the Quote class, probably, you have to refactor that one too at Samurai class to match ICollection):

namespace SamuraiApp.Domain
{
    public class Battle
    {
        public Battle() 
        {
             this.Samurais = new HashSet<Samurai>();
        }
        public int BattleId { get; set; }
        public string Name { get; set; }
        public ICollection<Samurai> Samurais {get; set;}
    }
}

namespace SamuraiApp.Domain
{
    public class Samurai
    {
        public Samurai()
        {
           this.Battles = new HashSet<Battle>();
        }
        public int Id { get; set; }
        public string Name { get; set; }
        public List<Quote> Quotes { get; set; } = new List<Quote>();
        public ICollection<Battle> Battles { get; set; };
    }
}
