JWT middleware setup

  // Configure JWT services
  builder.Services
      .AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
      .AddJwtBearer(o => {
          var Key = Encoding.UTF8.GetBytes("12345678901234567890123456789012");
          o.TokenValidationParameters = new TokenValidationParameters
          {
              ValidateIssuer = false,
              ValidateAudience = false,
              IssuerSigningKey = new SymmetricSecurityKey(Key)
          };
      });

  // Use authentication / authorization middleware
  app.UseAuthentication();
  app.UseAuthorization();
