An unauthenticated access group, also known as a guest access group, provides limited access to application or network resources for unauthenticated users. Typically, unauthenticated users have access to only the rules in the rulesets in the PRPC:Unauthenticated access group. This access group is referenced in the requestor type instance named pega Browser. When configuring an unauthenticated access group, it is important to review the security settings of each activity in the rulesets to ensure that they meet the necessary access criteria for guest users.

Also  does this question give you the answer?

I don't think you guys are getting my point here

I am just doing some workaround on requestors

For the browser requestor, we can see operators from the requestor menu in Admin Studio

I would like to be able (if possible) to have an unauthenticated user on that menu ; whatever the way to achieve it
