OIDC logout implementation

I am trying to implement logout functionality using following documentation

I am able to call this url with openid token.
But when I redirect to protected url, instead of showing okta login page, my application page is getting displayed.
My assumption was once Okta session is removed from okta side then application should get okta login page as logout may have deleted to the relation with browser cookie

Can I delete the cookie on my browser which okta creates in application ?

hi @amitashokgadkari what do you have set as your logout uri within your OIDC application in okta and is it the same as your post_logout_redirect_uri parameter in your logout request?
