// Scopes! You must request the scopes you need to have the access token.
// In this case, we are requesting the user's identity (basic user info), user's email
// For example, if you do not request email scope while logging the user in, later you wont be able to get user's email via /identity endpoint when fetching the user details
// You can only have access to data identified with the scopes you asked. Read more at https://docs.patreon.com/#scopes

// Lets request identity of the user, and email.

// Simply echoing it here. You can present the login link/button in any other way.
