Have you looked at the Edebug section in the Elisp manual:

(info "(elisp) Edebug")

It's quite long, but IME you don't need to read all of it right away. For
starters, read the first chapter "Using Edebug":

(info "(elisp) Using Edebug")

In fact, for the longest time, this was basically all I knew about
Edebug... 😆 One additional command I often find useful: `e`, which allows
you to evaluate an expression in the context of the program being debugged.
