To enable forms you need add them to import section of your project-entrypoint namespace
(or some different namespace which will be loaded)
a) You can import them all by importing library root namespace
b) Or for more precise control - you can add them one by one.
After that, you can go to Aibox Forms UI and see
Change Library Forms
If you need to change one of the library form - you should copy it (as file) from library to your project /zrc directory and edit it there. To preserve your changes you commit them to git and push to remote git-repo.
Library Forms should not be edited manually - only used. Because these changes will not be pushed to upstream. And after restart you will get clean state of these forms.
