Get Items back from Queue

I add to the Orchestrator Queue 5 DataTable, using this code
stringVariable = Newtonsoft.Json.JsonConvert.SerializeObject(**DataTable**) in an Assign Activity.
It was added perfectly, Now I want to retrieve the DataTable from there, but it is now a QueueItem and I want it again as a DataTable, How can I do that?.
Can someone Help me, please?
Thanks in Advance.

we can retrieve back with GET TRANSACTION ITEM activity

were we facing any issue with that
