How to open the Project Sources table

How to show the project sources table:
The project sources table shows the Geo data sets used in the project and data imported by a user. The table shows:
- the name of the dataset
- the type
- the publisher of the dataset
- the number of features in the 3D model (count).
Notes
If the count is 0, this means the items in your project do not reference the source. If the data is a raster dataset, which technically does not contain features, but cells with a value, the value will be 1.
