"CS0246" error is thrown for the missing 'ThreadDTO' type when importing the "Creating and reading basic annotations" sample from the Unity Cloud Collaboration package

How to reproduce:
1. Create a new Unity project and install the Unity Cloud Collaboration package
2. In the Package Manager, open the Samples tab for the package
3. Import the "Creating and reading basic annotations" sample
4. Observe the Console

Expected results: The sample imports and compiles without errors
Actual results: A "CS0246" error is thrown because the type or namespace name 'ThreadDTO' could not be found

Reproducible with: 1.0.1 (6000.7.0a5)

Reproducible on: macOS Tahoe 26 (M1)

Note: The errors are cleared automatically after some time, errors appear before the scripts are compiled, by it takes around a couple of minutes and no background tasks are shown
