Launching a workflow after DAM Update Asset

I've got a workflow model that I want to run after DAM update asset finishes without modifying the DAM update asset workflow itself. I know that DAM_UPDATE_ASSET_COMPLETED event triggers at the end of DAM update, but I'm not sure how I can leverage this in my Workflow Launcher conditions. Is this possible, or is the only way to do this by creating an event listener with the workflow model logic inside?

All help is appreciated.

Thanks
