How to define an interactive function with multiple prompts

Today I tried to define a function that prompts the user for multiple arguments in a single function call.
I knew I need to use the
interactive form. But when I read the
it is a bit hard to read without code examples.
So I tried to tinker with it by trying this function:
(defun test-fn (arg1 arg2) (interactive "sEnter arg1: \nsEnter arg2: ") (message "arg1: %s, arg2: %s" arg1 arg2))
And it works as expected. The trick is to separate the prompts with a newline
This way, it defines a function an interactively-callable command that accepts multiple prompts in one function.
