Row.canExpand | Not seeing documentation or a trigger for this variable (conditionally make certain rows expandable)

Doc: https://react-table.tanstack.com/docs/api/useExpanded
Sandbox: https://codesandbox.io/s/github/tannerlinsley/react-table/tree/master/examples/expanding?file=/src/App.js

It would be helpful to have to variable to make certain types of rows expandable, but when done locally the canExpand variable on the row object is set to false, and I don't see a clear indication to trigger it to true.

Please tell me I'm missing something! Or is this variable no longer being used/triggered?
