❔ Include several include within get method

Helllo, i got an issue about including more than many entity relation to getAsync method. The reason is that causing a problem my getAsync method consist only one IIncludableQueryable parameter. But i have to include 3 different relation. Here is my getAsync method and my include method. GetAsync Method == >

Task<T?> GetAsync(Expression<Func<T, bool>> predicate,
        Func<IQueryable<T>, IIncludableQueryable<T, object>>? include = null);

Task<T?> GetAsync(Expression<Func<T, bool>> predicate,
        Func<IQueryable<T>, IIncludableQueryable<T, object>>? include = null);

Include Method ===>

public async Task<BookGetByIdDto> Handle(GetByIdBookQuery request, CancellationToken cancellationToken)
        {
            await _rules.BookShouldBeExistWhenRequested(request.Id);
            //todo && x.Include(x=>x.Author) && x.Include(x=>x.BookPublishers) find solution for the inclue more than many entity
            var book = await _bookRepository.GetAsync(x=>x.Id == request.Id ,include:x=>
                                                x.Include(x=>x.Category) &&
                                                x.Include(x=>x.Author) && 
                                                x.Include(x=>x.BookPublishers));
            var mappedBook = _mapper.Map<BookGetByIdDto>(book); 
            return mappedBook;
        }

public async Task<BookGetByIdDto> Handle(GetByIdBookQuery request, CancellationToken cancellationToken)
        {
            await _rules.BookShouldBeExistWhenRequested(request.Id);
            //todo && x.Include(x=>x.Author) && x.Include(x=>x.BookPublishers) find solution for the inclue more than many entity
            var book = await _bookRepository.GetAsync(x=>x.Id == request.Id ,include:x=>
                                                x.Include(x=>x.Category) &&
                                                x.Include(x=>x.Author) && 
                                                x.Include(x=>x.BookPublishers));
            var mappedBook = _mapper.Map<BookGetByIdDto>(book); 
            return mappedBook;
        }

its .Include(...).Include(...).Include(...) not .xInclude(...) && x.Include...

Also check out .ThenInclude if necessary, to let you include nested entities
