hi guys. I'm suffering from making signed transaction.

I'm developing some lazy minting code and I wonder how can I let wallet to make signed msg.

I'm using ton-connect and It only has sending msg function, I think there's no signing function.

how can I request wallet to make signed transfer? I know there's funcs in ton, and ton-core so that it will be not that difficult to make signed transfer with mnenomic key
but I have no idea how to make request.
