How to delete Models from the Shared Repository

Dear all

Problem:

I want to delete the models on the shared repository but cannot find how to do so.

Does anybody know  how to delete the content?

Background Info:

When testing the new possibilities of Visual Composer of NW 7.1 i just created some models without configuring anything. I created local models as well as models on the shared repository.

Now i got to start designing a cockpit for a real project.

Since we do not have a NWDI yet, we want to put the models for this project on the shared repository.

I found some documentation about configuring the names of software and development components (we did not do that yet)

However, before starting the real thing i wanted to clean up the mess i did before.

But like mentioned, i cannot find how to do so.

Private Models can be deleted easily, but the button "delete" is disabled for models on the shared repository.

In the documentation this is described like that - but there is no hint how to delete the shared repository models.

Thanks for your help and best regards

Martin
