I want to enable the manually created API by default

thank you very much!
I checked it out and tried it out right away.

But… Sorry. I think I need to take a few more hints.
I referred to the following article.

I created config/functions/bootstrap.js and created the file as linked.

However, when I restarted Strapi, this file was not loaded.

Is there any change in the way things are done since Strapi v4?
Do I need to use bootstrap() in src/index.js by any chance?
※ Ive tried that too, but its still not working.
