App Connector , 2 app same database


I tried all day to understand the logic, but I am lost.

I am using app connector to connect 2 App to the same database,

Application A ,I create a reservation, and I want this reservation to be created in the Application B database

Both app have app connector and the installed calls setup correctly

Then I have no idea

Thanks for any help

same thing, I connected 2 apps and now I am lost . How can I access from App A data or wf of App B ? The standard “Make Changes to” or “Create a thing” commands doesnot show data in App B
