Problem while running both the openedx mysql server and my custom plugin mysql server in django plugin app

Hello there, i have successfully built and run my custom plugin django app in tutor. Now i want to use the openedx mysql database with my custom django plugin app mysql database so that i can use the openedx data base for my app to add the new feature. But i have problem configuring. How can we do that? i am using tutor version 17.0.0. Thank you.
