[zod-openapi] Can't change style of object query params using extendApi

[vinicius507]

Greetings,

I'm trying to use @anatine/zed-openapi alongside @anatine/zed-nestjs to create a Dto for a query parameter as such:

const findManyUsersFilterSchema = extendApi(
  z.strictObject({
    name: z.string(),
    email: z.string().email()
  }),
  {
    title: 'Find Many Users Query Filters',
    description: 'The filters to apply when finding many users'
  }
)

export class FindManyUsersFilterDto extends createZodDto(findManyUsersFilterSchema) {}

Example usage:

   // [...]
  @Get()
  @ApiOperation({ summary: 'Lists users' })
  @ApiOkResponse({
    type: PaginatedUsersResponseDto,
    description: 'List os users returned.'
  })
  async listUsers(@Query('filters') params: FindManyUsersFilterDto) {
    // Redacted
  }

This Dto is meant to be used for validating a query parameter, but when I try to execute the request via the Swagger UI, it serializes the parameters in a unexpected way.

Expected: /users?filters[name]=foo&filters[email]=bar
Actual: /users?name=foo&email=bar

I understand that, using the @ApiQuery decorator from @nestjs/swagger, I can change the style of the query params serialization to 'deepObject', but I can't seem to do so using @anatine/zod-openapi. Is there any way to do so currently?
