Can you download the sample referenced at the page bottom in https://support.smartbear.com/testcomplete/docs/app-testing/desktop/qt/index.html to try it out, and does it work for you as expected?
As per your statement "According to support currently 6.7 and 6.8 are supported" is not inline with TestComplete documentation https://support.smartbear.com/testcomplete/docs/app-testing/desktop/qt/about.html#General reference.
TestComplete supports testing Qt applications that are built using a Qt-supported LTS version (5.15 and 6.2), and that were created with a Microsoft® C++ Compiler. You can use the compiler shipped along with Microsoft Visual Studio 2010 and later to compile your applications. Qt library can also be integrated into any other IDE (for example, into Qt Creator).
