Filter objects connected to the hub

Hi all,

I would like to upload a document and connect it with an object. When I use the Creator Widget I can selsct between all objects of that specific type. But I would like to filter these, so only the objects connected to the current hub should be shown.

I'm trying to use the filter and prefill the Hubshare ID with the Hub-ID.

But then the creator shows none objects. But in M-Files there are objects connected to the hub.

Is there any other way to filter the objects. Or what am I doing wrong?

Thanks in advance
