Playbooks with MDCA

I am attempting to integrate MDCA alerts with freshdesk as per the e.g. https://learn.microsoft.com/en-us/defender-cloud-apps/flow-integration

I have E5 without teams licenses.

I created the flow, Once from playbooks in MDCA portal and once in power automate directly and went to create a policy to test it out but the option "Sent to power automate" from the policy is always greyed out.

Alerts are not automatically detected in the flow unless the action in the policy is set to send to power automate which again is greyed as option in the policies.

Also playbooks tab in the MDCA portal does not show the flows I created before, It shows empty, Seems link is broken between MDCA and PowerAutomate.

Any reason for this, Any Idea about this? Thanks in advance.
