Issue: I am trying to access funds I had stored in a legacy Coinbase Vault 2/3 multisig wallet using the Coinbase multisig recovery tool (https://coinbase.github.io/multisig-tool/) . I have all of the necessary information to access the wallet, including the Coinbase xpubkey, the Shared xpubkey and the User xpubkey. Additionally, I have both the User seed and the Shared seed (encrypted) including the password.

However, I am encountering an issue with the recovery tool whereby the Vault wallet balance is not displaying upon entering in the xpubkeys in Step 1. Upon further research, it appears that there is an issue with the recovery tool referencing a Bitpay API endpoint that is no longer active. As such, the Coinbase multisig recovery tool is no longer functional. For reference, see the Reddit post and Bitcointalk forum post I'm referring to. Note, that I am experiencing the same issue described in the Reddit post (i.e. I have all of the necessary information to access the vault wallet).

Therefore, my question is, what are some other alternative methods to access the funds in my legacy Coinbase Vault 2/3 multisig wallet? Note, that the options should be prioritized in terms of technical complexity, with less technical methods preferred.

Thanks
