Error while implementing Generic interface in C#. How to decide?

Question

C++ / C#

There is the following code:

public interface IRequest<out TResponse>{}

public interface IPagedRequest<out TResponse>: IRequest<IPagedList<TResponse>> { 
    int Page { get; set; } 
    int PageSize { get; set; }
}

public interface IRequestHandler<in TRequest, TResponse> where TRequest : class, IRequest<TResponse> {
    Task<TResponse> HandleAsync(TRequest request, CancellationToken cancellationToken = default(CancellationToken));
}

You need to add a decorator to handle requests with pagination. I do the following:

public class PagedRequestHandler<TRequest, TResponse> : IRequestHandler<TRequest, TResponse> where TRequest : class, IPagedRequest<TResponse> {
    // ...
}

To which the compiler responds with the following error: "The type TRequest must be convertable to IRequest in order to use it as parameter TRequest in the generic interface IRequestHandler".
