How to look up for chain of arguments dependencies in C++?

Question

I'm new to C++ and I'm using Visual Studio Community 2019. Below are 3 functions: OnInput() passes FString argument to ProcessGuess() witch passes it to IsValid(). Is there any tool or extension for VS so I can click on local variable FString Word inside IsValid() function and see whole chain of transformations: Word<- Guess<- Input for this argument? I think "chain of arguments dependencies" is weird name for what I'm asking about, what is the proper name for it?

const FString ValidInput = "Yes";
 
void OnInput(const FString& Input)              // Take input from user
{   
        ProcessGuess(Input);
         
}   


void ProcessGuess(FString Guess)                 //Check if user have valid guess
{
    if (!IsValid(Guess))                  
    {
        PrintLine(TEXT("Your Input is NOT valid."));
    }
    else
    {
        PrintLine(TEXT("Your Input is valid."));
    }
}

bool IsValid(FString Word) const  //Check if user input is == ValidInput
{
    if(Word == ValidInput)
    {
       return true;
    }
    else
    {
       return false;
    }
}
