How to add development users for an extension app

[tymmtymm]

Hi, I have made an extension app based on this guide: https://developers.dropbox.com/extensions-guide#overview
The extension visibility is set to "Only Me", and I am able to test the extension in my own dropbox account. I want to share this extension to other dropbox users, so I have change the visibility to "All linked users", and I tried to get another dropbox account authorized by accessing the Extension URI directly. I can see that the extension/ app appears in https://www.dropbox.com/account/connected_apps but the app is not appearing in the "Open" menu (https://imgur.com/a/GPsZ1ZQ) Expected result : (https://imgur.com/a/SBlXWGu) 

What did I miss? 

Please advise, thank you

The extension will only appear in the "Open" menu for other users that have "linked" or authorized the app to access their own accounts via the OAuth flow. (Just accessing the extension URI itself directly won't do so.) You'll need to implement the OAuth flow in your app to allow other users to authorize the app to access their accounts. You can find information on doing so in the OAuth Guide and authorization documentation.

Okay, I had to logout and log back in to make the extension show up in my dropbox.
