Hey @fotoflo, welcome to the community!
There isn’t currently a Notion trigger for an updated database item. I’m sorry about that. The triggers shown in the screenshot were briefly made available and then removed. I’ve reached out to the team responsible for the Notion integration to try and get some more information about why and to see if there’s an ETA on any new triggers.
In the meantime, I’ve added you to the open feature request that we have asking for an updated database item trigger. This lets the team know how many users are interested in the feature and also means that we’ll send you an email if we have an update on this.
