[Help] Current Offsets

Hello, trying to update abrasives hack since he's not updated it any more.

could some be as so kind as to supply these offsets?
or at very least show me how i could go about finding the steam overlay address.

steam LocalBaseEntity (base)
steam Flags (offset)
steam Chat (base)
steam ChatOS (offset)
steam Menu (base)
steam Overlay (base)


Thank you so much.
