Archived case

HI, i have a question about archived case(s) visibility.

PROCESS DESCRIPTION

I have a process with initiator from a group called A.

The process involve actors from group B for certains human tasks and finally end.

SCENARIO

An employee from group B performs the last human task of the process and then the process ends.

The same actor change from group B to another group C (not involved in the process)

My question is:

We can get the link to the context of an open case with this "../API/bpm/case/{id}/context".
Do we have a similar thing to do this for an archive case?

If this does not exist, is there any workaround to access the BDM details for a closed case!

Thanks.
