Hi

I'm working on an openID connection to Auth0 in Umbraco 13. I've got the connection working and the autolink is creating the member successfully.

There is only one issue, I can't figure out how to set the field values for External.FirstName and External.LastName. They are not being filled in automatically, so I assume I have to specify this.

I've used this page as a guide, but still can't get it working: https://docs.umbraco.com/umbraco-cms/13.latest/reference/security/external-login-providers?fallback=true

The MemberExternalLoginProviderOptions OnAutoLinking callback function does provice a MemberIdentityUser object, but this object does not contain a FirstName or LastName property to set.

How do I set custom member fields on autolink?
