When inserting a composition, you are actually copying all of the nodes from its primary version into the currently open composition. The composition being inserted is not affected by the insert operation.

To insert a composition:

1. Select Composition > Open or press Ctrl + O(for Windows and Linux) or Cmd + O(for Mac OS).
2. In the File Browser that opens, select a version and drag it to the Player or Schematic view.
3. In the Gate UI that appears, swipe west to insert the selected version in your current version. The nodes from the primary version are inserted. The output nodes are not.
