Unable to invalidate access token

Hi Team,

I am trying to invalidate the access token on logout, but unable to do so.
I am calliing this api- http://localhost:8080/auth/realms/Realmname/protocol/openid-connect/logout to logout and invalidate the refresh token. This successfully invalidates the refresh token but not invalidate the access token.

Can you please tell how I can invalidate the access token?
