Open Safari (iOS) or Chrome/Firefox (Android) .

Tap your Profile Picture (top left) → Settings → Steam Store (or just scroll to find “Store”).

Once logged in, tap the hamburger menu (three lines) or your profile avatar → look for “Activate a Product on Steam” (sometimes under “Account” or “Store” submenu).
