Telegram isn't encrypted end-to-end, I don't believe. And I've never had a telegram account. Signal requires a new phone number and signal-cli running in the same docker instance as OpenClaw. Just a lot of digging in the works for something I just want to test out.
I would love to just set up an npub and DM to it. Whitelisting my human npub and blocking everything else, of course. The nostr plugin promises that, but doesn't quite get there yet. At least in the Umbrel package. Early yet.
For the moment, I'm just using the web interface. Which is fine.
