Any way to legitimately get the high quality digital PDF maps without having to completely rebuy the game.

[Tshi 19]

I bought this game ages ago and didn't think to buy the digital deluxe and only bought apex as itself when it came out. For various reasons having a high quality version of the maps to use for planning stuff out etc. would be very useful and I can't find a way to get them without searching online and downloading them off some dodgy website. Apparently you used to be able to upgrade in the steam store https://support.bohemia.net/arma-3/activation/96 however I see this nowhere anymore, perhaps I'm blind?

 

If anyone has a solution to this it would be greatly appreciated.
