Beginner Tutorial Problem

Hey There,
I am currently working on the FMOD integration tutorial with the kart simulation (https://www.fmod.com/unity-integrate#adding-sounds-kart-engine).
So far I made it to step 82. But somehow i can’t find the FMOD “Assembly Definition Reference” to complete this step.
I think I followed all the instructions so far what did I miss?
Really need help with that, otherwise I think i can’t continue with this tutorial.
kindly regards

If you look at the inspector that’s partly visible on the right side of your screenshot, you’ll see a list including “Unity.TextMeshPro,” “comm.unity.cinemachine” and “Unity.Probuilder.” This is the Assembly Definition References section of the inspector.
