Draft: Single-Logout for all (missing) components (XWiki, OX)
- XWiki: does not support frontchannel nor backchannel logout (see #38 (closed))
- OX:
- Backchannel logout does not work as OX's OIDC implementation is more strict compared to other implementations and is affected by https://github.com/keycloak/keycloak/issues/19220
- Frontchannel logout does not work as well due to another bug in Keycloak https://github.com/keycloak/keycloak/issues/17318
