Supporter Packs on Ps5?

Is there any ETA on when will the supporter packs be available on PS5? Do I need to install the ps4 version in order to upgrade my purchased packs?

You shouldn't need to install the PS4 version, just shop on the PS4 version's listing on the PSN store.

You might need to "own" that version, if you've never downloaded it before. I don't remember if you can "buy" a free game without downloading it.

Also, once you have your points, you can spend them right here on the website.
