rename fields in many-to-many relationship in EF core 5

Question

I Have this Entity Model Diagram

Where I have a many-to-many relationship between Licitadores and Ofertas and UTEs and Ofertas son when I create the database I have this

But I would like to use in OfertaUTE as primary keys LicitadorId instead UTEsLicitadoresId, OfertaId instead of OfertasId and UTEId instead UTESId

So in my mapped class

modelBuilder.Entity<LicitacionesEnUTE>().ToTable("OfertaUTE");

I add more fields (payload)

public class LicitacionesEnUTE
{
    
    public string OfertaId { get; set; }

    public int UTEId { get; set; }

    public int LicitadorId { get; set; }

    public bool Adjudicado { get; set; }

    public string Plazo { get; set; }

    public decimal PresupuestoOfertado { get; set; }

    public decimal PorcentajeFulcrum { get; set; }
}

}

But when I create the database I have this

Any idea, please?

Thanks
