How do i upload a project folder (packed) to Meta Quest 2 VR?

Hi. I have a project done in UE5 (for testing purposes), and connecting the VR glasses and running the app from my PC works ok.
Now i wonder how can i upload the folder to the VR headset itself to play it without having to connect the headset to any pc. Tried to just upload the project folder to the VR headset drive, just copy and paste it to the “download folder”, but cant execute the .exe in the glasses.
Its hard to find any information related to this very question (or i am not having luck with this). Can anybody give me a hint? Im not interested in publishing or anything, just making it work in the Meta Quest 2 headset and test it without connecting to PC.

Thank you very much!!!
