I applied on Monday 18th, and enclosed pdf printouts of my Activity statement from the Velocity website, my Velocity status (I have re-qualified and my expiry date is in the next few days), and the photo of my physical card. Not sure if I got lucky with not requiring further statements or if it was because my status printout had extra info. I have decided to ask Velocity for my statements just in case they get asked for.
I received the following message in the Qatar contact centre portal:
