How to create an example of request object?

Do we support example values for request objects?

		public async Task<ActionResult<IEnumerable<DummyDto>>> GetConfigurations(
			[FromQuery] DummyQueryDto query) =>
			Ok(await configurationRepository.GetQueryable()
				.ProjectTo<DummyDto>(m_mapper.ConfigurationProvider)
				.ApplyFilter(query.ToFilter())
				.ApplySorting(query.ToSorter())
				.ApplyPagination(query.Offset, query.Count).ToListAsync());
	}

How do I supply example value for this DummyQueryDto object into Swagger UI?

I use OpenApi, SwaggerUi3, AddOpenApiDocument - a really basic setup.

Is there a support for Swashbuckle.AspNetCore.Filters ?
