With the launch of the Notion API third-party apps can now use it to build Notion integrations.
The first time you give access to your Notion Workspace to another app, you can select which databases you want to share
But now, if you create a new database, the third-party app doesn’t have access to it, and so will not be able to use it.
If you want to share your newly created Notion database with an integration you just have to follow those 3 simple steps
1 - Go to the database page and click on the share button at the top of the page
2 - Click on the input text and select the integration with which you want to share it, in that case, Klippper
3 - Finally, click on the Invite button, that’s it, the integration can now use your database!
