Issue Linking Power Automate Flow to M365 Copilot Agent

Hello,

I am building an agent on M365 Copilot and using Power Automate to execute a set of actions together.

I successfully created and published the flow. However, when attempting to link the flow action to the agent, it does not appear in the interface. The interface indicates that one flow action exists (as highlighted in the screenshot below), but the page remains blank.

This appears to be an interface issue preventing the flow from displaying correctly. Could someone advise on a possible resolution, or should we escalate this to Microsoft Support? Kindly note that the flow is under the same environment where the Agent is built.

Any insights would be greatly appreciated.

I have exactly the same issue and came here looking for the answer. I'm not going crazy after all!

I've tested on various browsers and get the same weird inconsistency and missing flows, same as you. Sometimes it says "48 actions" and displays nothing.

I don't know if you've noticed but this same dialog is accessible under "Actions" when creating a more traditional Copilot. It seems to work, but still in a weird way, and does display the flows I've built.

It is very strange that I am still encountering the same issue. I noticed the same on traditional Copilot; it is showing, but the bug is in the agents themselves within the M365 Copilot Extensibility. I think we should raise a ticket with Microsoft Support as it seems to be a bug.

I have the same problem here.

Works in a regular Agent with the same flow, but when extending Microsoft 365 Copilot the flow does not show up.

The count says 1 action when searching, but the user interface is empty just like you screenshot.
