#Security Center3 debatiendo

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 .  

I've had multiple issues with the Security Center Insights job and have put in a few support cases. The first one fixed an issue and then other issues occurred so I put in another case.  Of course, all Salesforce did was put in another known issue (which is what they did the first time). Please upvote here if you're having similar issues! The Insights Job hasn't worked as expected since last October/November for me. Here's the Known Issue:  https://help.salesforce.com/s/issue?id=a02Ka00000mGsSu&isReported=Yes

. 

I am trying to activate the Security Center app inside my  Sandbox org. According to the documentation, I just need to tick the Manage Security Centre user permission on the System Administrator profile.

I do not have the option. Any idea how to proceed?

From the help documentation , steps are not pretty cleared .
