create site-to-site VPN connecting to TGW in another account

I created TGW in account A. Using RAM, I shared it with account B and the share was accepted. It is visible in account B in the TGW section and it's noted that it's owned by account A. In account B, when I choose to create a Site-to-Site VPN and elect to connect it to a TGW, the TGW shared from account A is not showing. Additionally, when I try this process through Terraform, it says the TGW does not exist. How can I accomplish what I am trying to do with VPN and TGW being in different accounts?
