Retrieving User Metadata with claims in Auth0 integration with SharePoint

When I tried to retrieve user_metadata as part of login, it is not returning. I tried adding user_metadata as part of request claims, still no luck. Any thoughts how to retreive use_metadata?

-webAppUrl:“http://mysharepointsite/
-identifierClaimType:“http://schemas.auth0.com/username
-claims:@(“Email|http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress”,
“User Name|http://schemas.auth0.com/username”,
“User Meta|http://schemas.auth0.com/user_metadata”,
“Email Verified|http://schemas.auth0.com/email_verified”,
“Client ID|http://schemas.auth0.com/clientID”,
“Surname|http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname”)
-allowWindowsAuth

where can I found list of valid claim namespaces with auth0?
