Cannot implicitly convert type 'MongoDB.Driver.DeleteResult' to 'T'

Question

I'm using MongoDB in my MVC project and am creating a utility function that I could use to delete records in database.

I am using :

• mongo db extension for C#
• C#(.net 4.6.1)

To method is passed record what I want to delete. I filter all recordings in DB by id of passed recording what I want to delete. Finding it I want to delete it. my method

public virtual async Task<T> Delete(EmailBlastDocument input)
        {
            var filter = Builders<T>.Filter.Eq(p => p.Id, input.Id);
            
            var collection = DocumentContext.DocumentClient.GetDatabase(DatabaseName).GetCollection<T>(CollectionName);

            return await collection.DeleteOneAsync(filter);

        }

But it highlights error on compile time

Cannot implicitly convert type 'MongoDB.Driver.DeleteResult' to 'T'

How do I fix this function to properly return the result of delete record to the caller? And how to properly delete record in mongoDB

I have create Update method what was took as example

public virtual async Task<T> Update(T input)
        {
            var collection = DocumentContext.DocumentClient.GetDatabase(DatabaseName).GetCollection<T>(CollectionName);
            try
            {
                await collection.ReplaceOneAsync(a => a.Id == input.Id, input);
            }
            catch (MongoWriteException ex)
            {
                switch (ex.WriteError.Category)
                {
                    case ServerErrorCategory.ExecutionTimeout:
                        throw new TimeoutException();
                    default:
                        throw new CirrusDocumentGeneralException();
                }
            }
            return input;
        }
