On android when loading a file - chrome wants access to camera

I looked at the webUSB support article and it indicates that it works on android.
I created a program and saved it.
I cleared the editor then loaded it.
When i click load button then click 'pick a file' link
I get the android window 'chrome needs access to camera and record video'
It then pops up 'chrome needs to record audio'
I click allow on both pop ups and it then offers 4 icons.
Camera, camcorder, audio and files.

Chrome already had access to storage.

How do i find my android version if you need it?
EDIT---
you go to settings/phone / software
My android version is 8.1.0
Samsung experience version 9.5
---END
Chrome is version 75.0.3770.101

Is there something missing on that pick a file link that would indicate to chrome that it only needs access to storage

読み込みフローとその「pick a file」リンクから始め、Android 8.1.0 の Chrome 75 で報告内容を再現してください。そのファイル選択のエントリーポイントがどのようにアクセスを要求するかを確認し、保存済みのプログラムの読み込みが、カメラや音声に関する不要な許可要求なしに完了することを確認してください。
