Nuget packages per group

Hi, i have a question about the package registry.

I have an pipeline which pushes the package as expected.

Now if i want to use this package in visual studio i have to add an source like this:
https://gitlab.com/api/v4/projects/[packageId]/packages/nuget/index.json

Generally I have one project which contains one package. That means i would have to add an individual source for each package.

Thats why I would like to have it on a group level. So me and my coworkers could add one source which contains all of our nuget packages.

I there a way to do this with the gitlab v4 api?

I have not found a solution with the api documentation.

I tried https://gitlab.com/api/v4/groups/[groupname]/packages/ which lists all my packages, but not in the correct nuget json format.
