I have to implement a backchannel logout in my application, here I am using selfhosted ory hydra for OIDC connect . I have 3 client application , if I logged out from 1 application then, how do we notify other client apps which is in the same browser (I am getting response to post logout uri corresponds to client app which initiates the logout, As per the openId documentation, an OIDC provider can able to notify other clients using their pre configured backchannel_logout_uri and parameter like logout token.But unfortuntely we are only recieving this response to only the client app which actually initiating the logout.)
