Created the draft as i especially am unsure with this line. Has anyone an idea what is the better way to collect the SessionId before the document is deleted? This case works only because the SessionId is also the document-key, but obviously this might change.

Waiting for aneoconsulting/ArmoniK.Api#650 before reviewing as it will change and this PR will be updated too.
