How to logout for OKTA OIDC application hosted behind AWS ALB

I have the same issue but I still don’t understand if there is a solution or not. The workaround is a rather poor one.

Basically, the AWS Application Load Balancer handles OIDC. The application receives x-amzn-oidc headers.

Can I extract id_token_hint =<id token> from those headers? What is the field id token in those?

Or is it something that AWS needs to implement in the AWS?
