Sidebar discussion Messages posted to activity stream are not shown in Polaris but are shown in Agent WorkspaceDescriptionSidebar discussion Messages posted to activity stream are not shown in Polaris but are shown in Agent WorkspaceSteps to Reproduce - In OOTB Tokyo instance, impersonate System Administrator- Open any Active incident and click on Discuss- Initiate the discussion and add a comment- Post the comment to activity using "Post to activity stream"Issue: The comment just posted does not appear in Activity Stream in backend while it appears in Agent workspaceWorkaroundThe behavior is working as expected. Sidebar discussion tiles and Sidebar message tiles are only visible from workspace, but not the classic UI of record pages. The work notes from classic UI of record page is using different framework as the activity stream from workspace.Related Problem: PRB1618807
