Assertion attribute Role mappings for SAML

I have SAML SSO as external identity sources working fine and looking for Assertion attribute for role mapping. SAML from identity source is passing values but i cant find the mapping name on the doc.

From identity source;

<saml:Attribute NameFormat=“urn:oasis:names:tc:SAML:2.0:attrname-format:basic” Name=“ROLE ATTRIBUTE NAME”>
<saml:AttributeValue xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” xsi:type=“xs:string”>Admins</saml:AttributeValue>
<saml:AttributeValue xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” xsi:type=“xs:string”>CMP Users</saml:AttributeValue>
</saml:Attribute>
<saml:Attribute NameFormat=“urn:oasis:names:tc:SAML:2.0:attrname-format:basic” Name=“lastName”>

Morpheus SAML;

is there any guide / document to configure role mapping?

Thanks.

I just fixed using this solution. Role Mapping is working now.
