How to obtain proof that we built a Power Automate Cloud Flow in a customer environment

We raised a help ticket with the Microsoft support team at Partner Network/Channel, who asked us to raise this ticket.

We are trying to attribute Power Automate Cloud Flows linked via PAL to our partner score, but some Flows are not appearing, despite us doing what is required based on what we can tell from the documentation.

They have asked us to obtain proof that we built the Power Automate Cloud Flow, but we are not aware of the way to do that. Can you please support. Thanks.
