Oh! System tags! That would definitely have been a better way to do it. We ended up querying for tasks in the "DevOps" project with the name "Interactive Session"

Oh no, I just saw the message @<1541954607595393024:profile|BattyCrocodile47> is this stills relevant?

Hi @<1541954607595393024:profile|BattyCrocodile47> , you can simply pull all interactive session tasks - they are all tagged by the interactive system tag

Is there some way we could programmatically list all current ClearML sessions?

We need a way to do that, maybe with the clearml-session CLI in order to populate the VS Code extension menu.
