How to act on issues/PRs "as" an organization?

Everything I’ve ever been able to find regarding Organizations docs indicates that it’s not possible to log in as an org account, and thus one can’t comment or otherwise act “as” an organization (only one of its members). But I saw this event today: dotnet locked and limited conversation to collaborators

Surely dotnet doesn’t get special tools that no one else can use, right? If I as an organization admin wanted to do something “on behalf of” the org itself, without showing normal users which admin did it, how would I do it? :grin:

This is mostly idle curiosity, as I’ve never needed to do such a thing. But in case the need presents itself in the future as my projects grow, I’d like to know how.
