Magento 2 how to do a query on custom collection

SELECT time FROM my_timeslot_list WHERE date = “2019-11-12” GROUP BY time;

How do I run this query on collection factory.

This is the code  $collection = $this->collectionFactory->create();
$collection->addAttributeToSelect('*');
$collection->addAttributeToFilter('date', $date);

But this isn’t correct. Is there anyway I could do the query in collection
