    There's a doubt I have. Shouldn't we have only considered those notifications that were sent for a product id, and id the user clicked them then we can attribute the purchase to that notification.
    We can't attribute a purchase to a notification not intended for the product

    It has not considered product_id?

    Would've been simpler if:
    1. In a first cte, grab attribution to all purchases AND their notif type in a simple left/inner join
    2. Aggregate all the notifs sent by type and left join to the cte to get conversions by notif type
    This get get to the conversion by type quicker and more efficiently (less joins)
