Refactor- name of the product going to be unique, why have to declare ToList ?

[Jeevananthan-23]

public async Task<IEnumerable<Product>> GetProductByName(string name)
        {
            FilterDefinition<Product> filter = Builders<Product>.Filter.ElemMatch(p => p.Name, name);

            return await _context
                            .Products
                            .Find(filter)
                            .ToListAsync();
        }
