Manifest validation fails when trying to create an application role with a backslash
A BAD_BadRequest messages is returned when trying to use backslashes for a role in the manifest. Please allow valid SAML attributes values to be passed in the role.

It would be great to be able to edit and manage SAML roles here and not have to use the Graph API which requires higher privilieges. An example of the kind of roles here https://docs.microsoft.com/en-us/azure/active-directory/saas-apps/alibaba-cloud-service-role-based-sso-tutorial#configure-role-based-single-sign-on-in-alibaba-cloud-service
Furthermore, using the GraphAPI is super dangerous, you can easily delete your application just by choosing DELETE and executing.
