Where to keep the application for marketplace?

Hello everyone,

I was not able to find this information anywhere on Atlassian Support thus I’ve to ask you for help. I’m going to publish the application for Bitbucket in Atlassian Marketplace. My application is OAuth and I don’t know where it should be kept - in the developer console (https://developer.atlassian.com/console/myapps/) or in my workspace on Bitbucket (Develop app section). I can’t find any information about the usage of the developer console - I’ll appreciate it if you can share some information with me.

Thank you in advance!
