How to use App for multiple users

I want to syn my activities with my custom system which have more than 1000 users every user will have separate pipdrive account they will syn their own activities with their own pipedrive account.
For that purpose I created App in pipedrive sandbox account I have done authenticate it using OAuth also created Activities, persons , Organization using api.
But my problem is its work for only 1 user where I created app.

Hello,

When you build an app on Pipedrive, the app only works for the Users on the account it was built on unless you send it for review and it is approved.

Please guide me how to create Pipedrive app that works for every user
