Discourse SAML plugin - How do I map to the "Web Site" profile field?

I am using the Discourse SAML plugin and I can’t seem to get a mapping to the built-in profile field “Location”.

My identity provider is sending it over:

            <saml:Attribute Name="website"
                            NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic"
                            >
                <saml:AttributeValue>http:\/\/PROFILE_WEBSITE.com</saml:AttributeValue>
            </saml:Attribute>

And I have a setting in the Discourse SAML plugin “SAML Attribute Statements” to map this incoming field to (hopefully) the Discourse standard field:

website:website

But it does not populate. I tried referring to it website, web-site, web_site but nothing seems to match.

Does anyone know the correct way to reference this standard field?

Thanks
