I am a beginner and have just started working with Unity 2022, Hololens2 and MRTK3. For my project, I am trying to enable gaze interaction such that when a person gazes at an object(eg. a sphere hologram) for more than a threshold amount of time(eg. 3 seconds), a text(textMeshPro) that was previously invisible becomes visible due to the gaze. I would really appreciate it if someone could guide me through all the necessary steps. I understand that I am supposed to use Gaze Controller but I cannot figure out how.
