Earning Qantas points on purchases

Can i still get my Qantas frequent flyer points if i made a purchase direct from the Microsoft online store and via the Qantas mall?

I made an eligible purchase on the Microsoft online store but i did not log into my Qantas frequent flyer mall first to then be redirected to the Microsoft online store.

I have the record and receipt of purchase logged with Microsoft but can i still use this to claim my Qantas points?

Plead tell me how i can claim my Qantas frequent flyer points from my Microsoft purchase.

Thank you!!!
