after MUCH struggle, and a paid consulting session, this appears to log us out properly:
(async () => { try { await feathersApp.logout(); window.location='https://dev-2XX8.auth0.com/v2/logout?returnTo=https://mydomain.com/proxyPort20004/' } catch (e) { console.log(e); } } ) () ;
who knew?? (answer was partially here Redirect Users After Logout)
if there is any sort of “cookbook” started, this might help out somebody else.
