    {
        public T EntityDb { get; set; }
     
        public class UpdateConfigureHandler : IRequestHandler<
            UpdateConfigure<T>,
            ConfigureOutputModel>
        {
            private readonly IConfigureRepository _repository;
            private readonly ITypeComposer _typeNameComposer;

            public UpdateConfigureHandler(IConfigureRepository repository,
                ITypeComposer typeNameComposer)
            {
                _repository = repository;
                _typeNameComposer = typeNameComposer;
            }

            public Task<ConfigureOutputModel> Handle(UpdateConfigure<T> request, CancellationToken cancellationToken)
            {
               //...some code here
            }

        }
    }

Call from my Api Controller method

ConfigureOutputModel outputModel = new ConfigureOutputModel();
UpdateConfigure<ConfigureOutputModel> updateConfigure =
                new UpdateConfigure<ConfigureOutputModel>() {EntityDb = outputModel};
var query = await this.Send(updateConfigure);
