Mixed array of custom type

[matte0080]

export class ActivityEventVisibilityRequest {
  @IsNumber({
    maxDecimalPlaces: 0,
  })
  @IsDefined()
  version: number;

  @ValidateNested({ each: true })
  @Type(() => ActivityEvent, {
    keepDiscriminatorProperty: true,
    discriminator: {
      property: 'name',
      subTypes: [
        { value: ActivityEventVisibility, name: EActivityType.VISIBILITY },
        { value: ActivityEventCiccio, name: EActivityType.TEST },
      ],
    },
  })

  @JSONSchema({
    type: 'array',
    items: {
      anyOf: [
        {
          $ref: '#/components/schemas/ActivityEventCiccio',
        },
        { $ref: '#/components/schemas/ActivityEventVisibility' },
      ],
    },
  })
  events: ActivityEvent[];
}

ActivityEventVisibility e ActivityEventCiccio are subclass of ActivityEvent. In OpenApi doc i see this.

What i need to do for see ActivityEventVisibility e ActivityEventCiccio in events: ActivityEvent[]; type? Actually i see ActivityEvent in schema space and in example area.

In debug i see this. I think it is wrong.
