nit: should fit in one line?

Done.

remove this and make the previous a Wait(2) ?

1) I think you should be able to write this as selector='a[aria-label="Page 2"]'
to keep consistent with _SEARCH_BOX_SELECTOR above. (And, as far as I can tell,
should work even before landing https://codereview.chromium.org/2559503002/)

2) Maybe also introduce a _PAGE_2_SELECTOR?

+    action_runner.Wait(2)
+    action_runner.ClickElement(selector='a[aria-label=\'Page 2\']')
+    action_runner.Wait(2)
+    action_runner.ScrollPage()
