How to use Functional Test and Automation Driver spec together?

Hi! Lets say I have some spec:

BEGIN_DEFINE_SPEC(FAutomationDriverSpec, "System.Automation.Driver", EAutomationTestFlags::ProductFilter | EAutomationTestFlags::ApplicationContextMask)
FAutomationDriverPtr Driver;
void FAutomationDriverSpec::Define()

And I also have Functional Test:

void AGameLaunch::StartTest()

How can I tie those 2 together? So that I could run that spec inside functional test?
