I am building c# application for connect DropBox.
For DropBox authente, I display dropbox login page within IE embed browser using api like this,
var authorizeUri = DropboxOAuth2Helper.GetAuthorizeUri(OAuthResponseType.Token, ClientID, new Uri(RedirectUri), state: oauth2State);
AuthBrowser.Navigate(authorizeUri);
In the login page, sometimes appear "Sign in with Google" button, but almost not visible.
I want to visible always "Sign in with Google" button or never visible.
How can I do this?
