weapons – Can a Halfling Sling Staff double as a Staff?

I don’t see anything in AoN’s description of the Halfling Sling Staff that says so, but the abilities of the Staff Acrobat archetype seem to imply that a Halfling Sling Staff doubles as a Staff to some degree (Leveraging Strike and Pivot Strike especially).

Can a Halfling Sling Staff also function as a Staff? I believe in Pathfinder 1e it could be used as a club, but I’m not sure if that has been brought over into Pathfinder 2e.
