Give me a hand: About sending files from Unity Apps to AWS S3 on Oculus.

Hello.

Are there any developers who send any files from Unity Apps to AWS S3 on Oculus Device?
If you are so,please give me a hand.
Details as belows.

Background:
I'm developing an Unity application which records voice and save it into ".wav file", and send it to AWS S3.
Now I can see those features on my Unity editor,which runs on Windows OS(also build setting  in Unity is Android).
But that Unity application can't send  ".wav.file" to AWS S3 when I build  it on Oculus GO.
I check all network settings, SDK settings,project setting, and  also there seems to be no compile errors on my App.
(Definitely "wav files" are made, just I can't send those files to AWS S3)

I want to know:
Are there no services that can send to files to the  Internet on Oculus Go,Quest devices?
If you know about the services on Oculus devices,
,and If you have developed Apps like as Apps I developed, please let me know.

Thank you in advance.
