Digital Ocean Runner - Snapshot

Hello everyone!
Anyone knows if I can use snapshots as server image in a pipeline that use digital ocean runner?
In documentation, there are only examples with this image (docker-18-04), but I made a snapshot with Ubuntu as base, and already installed all the dependencies that I need to build my project.

have you tried setting image to the snapshot slug?
