Not able to run scheduled test runs in Copilot Studio Kit using Power Automate Flow

I am trying to trigger scheduled test runs via Power Automate Flow in copilot Studio Kit. The test is getting created successfully and it runs as well, however I am getting no response from my agent. The responses are simply blank. When I checked the test flow runs I see that the bot is responding something related to sign in.

When the test runs is duplicated manually it runs perfectly. One thing to note is that when I manually create test runs, it does open a sign in popup. The documentation does not mention how can I provide headless authentication in my flow.

Things to note:
Agent Configuration is being authenticated using Entra ID v2 and I cannot run it unauthorized due to client requirements.
