What happens to your Steam purchased expansions/DLC if you unlink your account?

I believe she may be able to pay her sub through her Steam wallet, but I'm not sure. I don't think you can unlink an account. You could also explain the situation to Steam and try for a refund. SE is super BS to try to work with for this kind of thing.

Attempting to select "Steam payment" from Mogstation itself is blocked as the website checks for whether the account's region aligns with the steam region(Steam region is Germany, Square Enix account region is North American). Unless there is some way to purchase the gametime on Steam itself I don't see this working. Any and all attempts at payments are faced with the error code stating the use of a VPN(not the case) or asking to change the address of the account, which is pointless as the country cannot be changed, only the location within it.
