Wix App collection installation and testing problem

Question:
I have generated an app in Wix Blocks and I added a collection to store information from the dashboard when you login to the app (some data is fetched from the backend at the same time). The app installation creates the collection on a test site that I have created my self, and it is visible in the website’s editor under My Collections. When I try the app installation on a website that I am just a developer on, then it does not create the collection under My Collections when I install the app. I have tried changing the permissions, but nothing has helped.
Anything I am missing or have misunderstood.

The error WDE0025, The @supersaas/supersaas/SuperSaaS collection does not exist. You cannot work with a collection using the Data API before it is created in the Editor.

No such error gets thrown on the site I created for testing only the one I am not the owner but a developer on.
