Hello everyone.
This 80k-word how-to is ready to publish but I have one huge concern. The TOC takes up 10 pages and makes the book feel overwhelming before you even start. I expected it to appear collapsed to H1 headings (which would then be clickable to expand).
I realize you can limit the headings that appear in the TOC but then those headings won't appear at all. Since it's a how-to it's important for readers to be able to find what they're looking for, so I really don't want to eliminate subheadings.
I found the same query a few years back
here, but was wondering if there is any easier way to do this (novice here). I read Ducks' reply to that thread several times and
think I get the gist, but was hoping there might be a more automated solution three years down the road.

Maybe even a plugin or third party tool people are aware of?
Thanks everyone...
