Use Cloud IAS users as Cloud Platform Mobile Service Cockpit authentications

Hello experts,

I am planning to use IAS users as the developers/admin in SAP MTP Mobile Services cockpit.

I am following this blog post but a bit lost on the way. I have done the part in IAS tenant admin console and established SAML2 trust (by uploading SAP Cloud Platform subaccount SAML metadata).

In IAS tenant admin console: application 'mobileServices'

I have created the role collection in SAP BTP subaccount as well to match Group in IAS.

But how to point the SAP Cloud Platform Mobile service cockpit link to IAS login page. It still redirects to SAP ID Service login page.

Best regards,

Sumit
