Testing Unity projects with Test Complete

I am hoping to test a Unity application that we use to prove our framework is working. It is essentially a bunch of buttons and UI elements, some are custom elements built off of Unity's framework and some are default Unity assets. 

Forgive me as I am new here and I am just trying to assess if this tool will do what I need it to do. I have been trying the test recorded approach and also manually modifying the recording trying to find elements but it only returns the game view and not any of the elements within that view. I can test with the recording version but it is very particular on timing and resolutions. 

What I was wondering is there any way for me to find the button elements within the game view in Unity? The game window process shows as having no children. I also checked all other window processes associated with Unity and there are no children or other elements to navigate to.
