How to protect custom functions I have written in code?

You can use some of the features of Creo by using the web link.
However, the features we created here are in html format and run in the built-in browser.
In other words, it is shared with html files, and our effort is easily exposed to the outside world.
I think you need some other way to protect some of the features you created with these web links.

The first way to think about it is to create a toolkit. But this is a fee, and it seems difficult to learn.
The second way to think about it is to have these web links function as a ribbon with j-link.

The second method seems to be feasible.

Here is the question.
1. Can I create a Ribbon that can easily work with creo's specific features (create frequently used parameters) like web links via j-links? Can these generations protect code from the outside world?

2. Can I apply the code created with the web link directly as a ribbon? Is this how you can protect your code from the outside world?

thanks
