Update workflow search attributes from client

We want to update completed workflow execution search attributes from external service or another workflow. Just add some attributes to find this workflow in list queries.

Is there any way to do it?
Found UpdateWorkflowWithOptions method in sdk, but there are no any reference for it in docs

Currently cannot update custom search attributes (or add new ones) for completed executions via api. Think only way would be to try do it manually in your visibility/advanced visibility store.

Regarding UpdateWorkflowWithOptions, it cannot be used on completed executions.
