[feat] Could I add params to handle auto-close after iframe load successfully

[vctqs1]

Here is my cases

• signout silent Salesforce IdP logout load via iframe
• Salesforce automatically redirects to https://www.salesforce.com/ap/?ir=1, resulting in a response header of X-Frame-Options: SAMEORIGIN. This prevents the iframe from loading, causing the logout process to fail.

Because Salesforce is not support post_logout_url. so I've to do that by myself and help them redirect to my login page after logout https://salesforce.stackexchange.com/questions/254591/openid-connect-single-logout

Expected: auto-close iframe and redirect by myself or maybe expect fn to createSignoutRequest then I'll do my own code to do that
