FOR GOD SAKE, IS IT SO MUCH TO ASK FOR A FUNCTIONAL PICKER LIBRARY?
Basically everyone is adding storage connectors to their products, and working with OneDrive feels like hell. !!!!
Picker v8 does not work with standard Microsoft Graph auth flows. The picker expects a different audience than the Graph token, which makes it impossible to authenticate users properly and then let them pick files. Why do I have to jump through undocumented hoops just to pass a token? !!!
Picker v7 is impossible to integrate for personal accounts because it ignores the provider token and piggybacks on the browser session. That breaks server-side connectors and any app that needs to use its own OAuth flow. !!!
v8 also piles on extra complexity (scopes/audience/silent refresh) with no clear, end-to-end sample. Meanwhile, Google Drive: drop in the picker, pass the token, done. It just works. !!!
