Two things i need help with from bitcoin experts please:

1. just installed the bitcoin core v.22 full node on mac Big Sur, but can't connect my Trezor with the UI.
can some experts please advise how to install the HWI, currently when I create a new wallet the option for "external signer" is grayed out, not an option for me to use my trezor with.

2. how can i find my full node .onion address so i can use an electrum server with my own node remotely?


thanks in advance！
