@@ -184,6 +184,7 @@ The example currently supports the following commands:
 - `attach-view-hierarchy`: Adds a `view-hierarchy.json` attachment file, giving it the proper `attachment_type` and `content_type`.
  This file can be found in `./tests/fixtures/view-hierachy.json`.
 - `set-trace`: Sets the scope `propagation_context`'s trace data to the given `trace_id="aaaabbbbccccddddeeeeffff00001111"` and `parent_span_id=""f0f0f0f0f0f0f0f0"`.
+- `capture-with-scope`: Captures an event with a local scope.
 
 Only on Linux using crashpad:
 - `crashpad-wait-for-upload`: Couples application shutdown to complete the upload in the `crashpad_handler`.
