Hi,
I lost my client Secret, I remember that it's not possible recovery it but I don't know how to create a new Client ID and Secret. I tried to go into INtegrations but when I press "API key", I can see that not possbile with my plane free, but I don't want a second Client credentials, I want to cancel the actual clinet and create a new . I need this informtaion to create a app of MIT Inventor. Can you halp me?
