Can not logout when auth via openid azure

I use openID auth Azure. When I press LogOut, page is reloaded but user is still signed in.
I set config in Azure

Logout URL
This is where we send a request to have the application clear the user's session data. This is required for single sign-out to work correctly.


Is there sth more that I should do?

Right now the OIDC authenticator only logout on XWiki when you click logout (your Azure auth status does not change). But if you access any non public page of the wiki then the authenticator is called, redirect you to Azure and back on your wiki, authenticated.
