How do I find the full path to my Vertex Data Store to use it for grounding a GenAI chatbot on the Vertex AI Studio?

I am trying to create a chatbot with text-bison and would like to ground it with a set of PDF documents. I have already created a vertex Data Store.

​

However, the form asks for Vertex Data Store Path in the format project/<Project ID>/........

​

I have no idea how to obtain such a path for a vertex data store. The documentation asks me to go to the vertex AI data store and click on more details, but no such option is available.

​

Any advise would be greatly appreciated.
