Help Needed: Adjusting Screen Size in Unity Environment on Meta Quest 3 Headset

Dear Meta Community,

I am reaching out to seek guidance on a specific issue I encountered while working with my Meta Quest 3 headset and Unity environment.

Recently, I developed a 3D Unity environment that I'm excited to explore using my Meta Quest 3 headset. I successfully downloaded the SDK Meta package and connected my headset to my PC running Windows. Upon entering the Unity environment through my headset, I found myself fully immersed.

However, I now find myself wanting to adjust the screen size within the Unity environment. Rather than the current setup, where the Unity environment covers my entire field of view, I am seeking to have the environment displayed as a smaller square. This adjustment would allow me to maintain immersion in the Unity environment while still being aware of my surroundings.

Could someone please provide guidance on how to achieve this? Any assistance, tips, or resources would be greatly appreciated.

Thank you in advance for your help and support.
