Repaints for FS2024 A300 purchased from the in-game marketplace?

[AlisterC]

Hi all, complete forum newbie, forgive me if this question is already asked, I've had a bit of a search and will keep searching. 
I recently bought the A300 on the FS2020 marketplace and then bought the upgrade in FS2024. (sorry, don't know if this means it's compatible or premium version). To my surprise the FS2024 is then only supplied with planes in inibuilds factory scheme, and an all over white scheme. I'm pretty sure all the advertising photos in the marketplace have the aircraft in various paint schemes. 
Can anyone please tell me how to get some liveries for the FS2024 addon? I've checked flightsim.to, but there's not a lot there. I assume I can't align my marketplace purchase with the inibuilds manager for liveries via that system?
*sorry, but the FS2020 marketplace version was about $20NZ dollars cheaper than from the inibuilds website for my New Zealand currency. I don't earn US dollars or GB pounds, so it's expensive here, and that made the difference between buying it, or not. I absolutely love the plane though, if that helps! Thanks 🙂
