Look for psi method annotations with plugin

I am trying to build a plugin that gives me all the names of functions in a file that have a the Junit.Test annotation. So this example class would return testFunction and testFunction2 but not testFunction3.

public class ThisIsMyFIrstTestClass {

    @Test
    public void testFunction(){

    }

    @Test
    public void testFunction2(){

    }

   
    public void testFunction3(){

    }
}


I then use this function to get my methods:

PsiJavaFile psi = (PsiJavaFile) e.getData(LangDataKeys.PSI_FILE);
PsiMethod[] methods = psi.getClasses()[0].getMethods();


Now All I want to do is something like the code below but the method isAnnotationPresent is not allowed on the PsiMethod object. Do anyone know how this is done?

ArrayList<String> testFunctions = new ArrayList<String>();
PsiMethod[] methods = psi.getClasses()[0].getMethods();
            
    for (PsiMethod method : methods){
          if (method.isAnnotationPresent()){
                 testFunctions.add(method.getName());
           }
    }
