Based on my understanding/recollection of `expect`, the concept is that you're scripting a command/process (or command sequence) via a "terminal connection" (or basic stdin/stdout), based on the (either complete or partial) "expected" dialogue response.
I guess that might in theory be possible to script a TUI with but I suspect it'd get pretty convoluted over an extended period of time.
(BTW I mentioned this in a comment elsewhere in this thread but check out https://crates.io/crates/termwiz to avoid re-inventing the wheel for a bunch of terminal-related functionality.)
e.g.
1. make initial connect over ssh (e.g. spawn ssh cli process) 2. expect "login: " response 3. send "admin" 4. expect "password: " response 5. send "password" 6. expect "$ " 7. send "whoami\n" 8. etc etc
