Thanks for your answer !
I tried and it seems to work. But now …
When i’m at the URL http://localhost:8080/about#access_token=*******&scope=channel%3Amanage%3Apolls+channel%3Aread%3Apolls&state=c3ab8aa609ea11e793ae92361f002671&token_type=bearer
What am i supposed to do ? Just catch the “access_token” param value from the URL ?
