[keycloak-user] RP-initiated backchannel logout

Hello, My RP should support dropping user's session by admin. I need to drop KC session together with RP's session. But I can't use frontchannel here as admin is dropping session for another user. So RP-initiated backchannel logout is required. I see no docs about this functionality in KC. We use OpenID Connect between RP and KC, so I've searched protocol specs. From section "3. RP-Initiated Logout Functionality" of https://openid.net/specs/openid-connect-backchannel-1_0.html and from section "5. RP-Initiated Logout" of https://openid.net/specs/openid-connect-session-1_0.html one can conclude that sending backchannel request to end_session_endpoint with ID token should drop the session on KC side. Could you please comment, is my understanding correct?
