Get last succesful materialization in asset check

[data-ux]

I'm trying to implement an asset check that compares the asset being checked to the last succesful materialization that was persisted.

I'm using context.instance.get_latest_materialization_event() as described in #14311, but the event that is returned is the current materialization that is being checked. I have confirmed this using the timestamp property.

So how do I get the last succesful materialization that passed all checks and whose state was actually persisted by the associated I/O manager?
