Unfortunately, this only works with Companion and not with the compiled app (APK), as there are still some bugs and permission issues, as I already predicted:

Testing the next release of MIT App Inventor (nb187)

Yes, maybe, but we should have been given the opportunity to test it on the test server until the very end. I'm pretty sure that there will be issues / bugs with the File component and also with READ / WRITE permissions after the targetSdkVersion = 30 update. I have done a number of tests with Niotron and (also) found some serious issues / bugs there.
