App connector setup

Hello,

I am trying to share data between two apps. Can’t find clear instructions on how to do this using the Bubble App Connector.
I have two apps, both used for entering the same information for different suppliers, I am doing this so that one supplier doesn’t see the others data when the enter it and doing searches etc. (there maybe an easier way, but I am unsure).
What I want to do is to be able to call up data from App 2 into App 1 so that I can do a comparison of products.
How do I setup the connection so that I can do this?

So essentially it will be a search box that will search both databases and returning multiple results that can then be selected and compared on different categories.

I hope that made sense, thank you in advance
