After executing a natural language browser action, allow the action output to be expanded to show additional detail about what was done.

• Action output can be expanded from its default collapsed state

• Expanded state reveals additional details of the action (e.g. specific tabs affected)

• Expanded state includes relevant items (e.g. list of closed tabs with favicon and title)

• Expanded content matches the result of the action performed

• Expanded state maintains the summary message and Undo button

• Undo behavior remains consistent in expanded state

• Expanded/collapsed state toggles per design (e.g. chevron interaction)

• Transition between states is smooth

• Expanded state layout is consistent and readable

• No impact to standard chat responses or behavior
