Thanks for adding tabs.In addition to the changes, the functional testing code at https://github.com/elastic/kibana/blob/main/test/functional/services/inspector.ts#L191 should be updated. The inspectorViewChooser button no longer exists so there is no need to click it and instead, the tab can just be selected directly.

Just tweaked the functional tests. Not 100% sure I correctly tested them locally. I got no failures when running:

node scripts/functional_test_runner --config test/functional/apps/home/config.ts

But running it with --grep="inspector" did no tests, so I’m not sure I was targeting the right config.

node scripts/functional_test_runner --config test/functional/apps/home/config.ts --grep="inspector"
