Maito uses Plain to do the work and replies where you asked.
How to connect Plain
Open Connections in your workspace and choose Connect next to Plain. You sign in to Plain in a new tab, and that's the whole setup. Name the account and choose Workspace under who can use it. That's the only time anyone signs in: your whole team, shared chats and Loops can use Plain from then on. Or skip ahead and ask for the work: Maito sends you a link if Plain isn't connected yet.

No. One person connects it once and chooses Workspace. Then everyone in the workspace, shared chats and Loops can use Plain, without signing in themselves. Choose Only me instead to keep it to your own chats.
No. If a request needs Plain and it isn't connected yet, your agent sends you a link. Connect it, and the work picks up where it stopped.
Yes. After you connect, turn off any Plain tools you don't want Maito to use, such as the ones that change data. Tools Plain adds later stay off until you turn them on.
