File reading problem with Android 11

Anke, thanks for your interest, could you give me a concrete example of how to set MANAGE_EXTERNAL_STORAGE with appinventor?

I remind you that I have to read, in the Download folder, a file saved by another app...

Unfortunately we are subject to these strange initiatives from Google which only create avoidable problems...

I followed this guide but the settings window opens to give permission to the app but my app doesn't appear in the list at all...??
