Automated workflows. Do you document them?

I've become curious about no-code operator's
and their workflow processes.

In particular, automated workflow planning.

is it worth planning at all?

With complex automation, do you feel the need to have a copy of how "things" connect outside of the automation platforms you use for them?

if yes do you use?:

is it visuals (arrows & boxes)?
is it text?
what platform?

Would love for you to share your thoughts
