Did you already unlocked them?
Because it's no longer possible as far as I know :
Scorch and GWENT T-shirt:
No longer available to obtain. These items are only available to use for Cyberpunk 2077: Phantom Liberty players who redeemed them before December 31st, 2023. Players who did so can find these items in the stash in V’s apartment after launching the game via REDlauncher.
