Salesforce Security Center -> Security Investigation not visible in object setting

I have been following "https://help.salesforce.com/s/articleView?id=xcloud.security_center_agent_setup.htm&type=5

" to setup new Security Agent in Salesforce. 

After assigning all required Permission set i am not able to see Security investigation tab in Object Setting . 

And for Configuration tab i am to see it in object setting after making its visibility as Default On still there is not option to add that tab in any app page .
