xGov Testing Voting Session Live on Testnet for the next 6 days

I use the Algorand node software to build my transactions, then I go on my dedicated/encrypted/airgapped laptop to sign those transactions. What am I supposed to do here?

In other words, with my current setup, how do I not compromise my security to vote in xGovs?
In the final version, will there be an “other-wallet” option that gives us the “–app-arg” or “–app-input” JSON of the resulting vote so we can manually build our own transactions?
Something a bit like what we currently have in regular Governance, where it gives us the correct note to attach to our transaction.

I don’t consider inputting my seed phrase on a phone or tablet connected to the internet as an actual solution.
