Hi Apex gurus, experts, masters, and professors,
I am trying to export one application from my workspace to my co-worker's workspace, but so far we can only export & import the application (pages) - without the tables and data. It seems there is no straightforward way to export tables from the Object Browser. I already tried the Generate DDL script from menu SQL Workshop > SQL Script, chose the tables, but got this error when my co-worker tried to install the script to his own workspace:

I also looked into this thread: Export APEX application, DDL and data, which suggest SQL Developer to do the table and data export. But the problem is I am using Oracle Cloud Apex as a Service. I don't know how to make remote connection to it.
Is there an easier solution for this? Any help will be appreciated!
P.S. I am using Apex v5.0.3
