Get User info from his access_token

Thanks markd! This is what I get from the req.user object:

{ iss: ‘https://DOMAIN.auth0.com/’,
sub: ‘AXhOpnsWfvIa718SZ7dXC3uHPST8fE7p@clients’,
aud: ‘https://DOMAIN.auth0.com/api/v2/’,
iat: 1580246238,
exp: 1582838238,
azp: ‘AXhOpnsWfvIa718SZ7dXC3uHPST8fE7p’,
gty: ‘client-credentials’ }

I don’t know if I am looking at the right oject, but the access token itself is just a string, is there a way to parse/decode it to get the email?

Also, I am ery interested on knowing how te add the email scope or rule to get that info when my users log in with their Database email/password credentials or SSO credentials. Thanks!
