Can you make a video about "customize your sidebar entries"

1

It might be easy for you experts, but for beginners like me, it’s hard to follow the tutorial. can you make a video?
If creating sidebar entries can be as easy as making a list filter, that would be great.
Just input glyph list, select language, click generate, done.Is it possible?

This is already possible with a List Filter.

Custom sidebar entries, as described in the tutorial, are useful if you need more (such as a hierarchical nesting of sections or a custom icon).
