Question
I created a custom entity. Where can I find it now, so I can connect it to a data source and use it?
Answer
Here's how to see the entities that are not connected at the moment:
Navigate to Insights drop-down menu and choose Data sources option;
If there are any entities that are not connected to any of your data sources in your account, they will be listed at the top of the screen.

NOTE: You need to have the required permissions to access the Data source section in your account and see entities that are not connected at the moment.
