i'm not having any issues running the kiosk with grafana 9.4.3, is it hanging somewhere, any logs?

[NissesSenap]

So I literately left my job yesterday so I can't access those files any more.

But as I tried to explain in #80 this is the issue of not being able to define the id vs uid of the target play list.

I don't keep my grafana instances consistent through a database but rather through gitops. So when my grafana instances restarts due to kubernetes moving it around or what ever I will get assigned a new UID. And due to this it's unable to find my playlist.

So I need the old id functionality to be able to know what I should configure as target URL in kiosk since the ID is deterministic.
Another option is if we could add the functionality of looking for a playlist name instead of a specific uid/id.

I updated the PR subject to make this a bit more clear @briangann
