[Feature] Allow listing of members across bridges

[patcon]

I wonder whether we could create a shorthand for helping people find members across bridges.

An ephemeral slash command might work: (only seen by sending user)
https://api.slack.com/slash-commands

Feature as imagined is slack-specific, but need not be.

A Slack slash command is just an integration that would be set up in Slack UI to hit an endpoint -- it could run off a "hook", whose precedent was already set up rocketchat hook integration

Or does this this seem like scope creep? I could understand that perspective :)

I want one solution for all bridges, probably will be by talking and sending commands to the bot

Ok, I'm grateful that you see it as helpful too! Do you feel it's important that the command/response NOT be public when possible to avoid?

If you wanted a list, it seems important it should PM you -- but checking to see if someone is "online" could still be really useful and not as spammy ...
