Upgrade flex-objects to v1.0.2

Perhaps I am still not used to the use of Grav. But I did an upgrade to flex-objects v1.0.2. What I discovered was that my own .yaml file in blueprints/flex-objects of the plugin was gone.
I put my specific .twig files already in the themes templates environment.

I thought that blueprint folders would be safe during an upgrade.

My question is where can I put my own specific flex-objects .yaml files so that it is secure during a new upgrade? How will Grav point to this place so that the yaml file is read. Is there in de Learn environment a page which gives me a direction.

Again thanks for answering.

If you're talking about config Yamls, then every plugin has instruction to copy first to /user folder depending on where you keep your configs. If you edit configs via Admin panel plugin, then it does this automagically. Usually it's /user/config/plugins/plugin-name.yaml, but I keep them depending on environment - /user/env/grav.local/config/plugins/plugin.yaml or /user/env/www.my-grav-page.com/...
