As long as you have direct and legitimate business purpose, direction, and/or permission, sure, the AP office can be entered.
We go in there to drop off training receipts (when we do a recovery) even if there's no one in there (we promptly leave), and we've been invited in as cashiers a few times to identify suspects on camera after a recovery if AP is unsure of the description.
Before PS5s and Xboxes could be sold in-store during the pandemic, that's also where we kept the consoles for OPU and DU (marked it as hold location FOS A099) so the Fulfillment team was in and out of there all the time putting consoles away, and then Service Advocates were in there to get them out for the Guests.
