WebViewer1 access to local files on tablet

Is it possible when I have the Webviewer1 to let the webviewer have access to the local files on the tablet?

I created an app in MIT App iNventor with 2 buttons. When you click on 1 of a button a website will appear in Webservice. In this website its need to upload a file from local storage.

When user is click button 2 a another website must be appearing in the webviewer with rights to the local data on the tablet.


The build-ini WebViewer can not open file chooser.
You need to use custom webviewer extension, search it from community forum please.
