In my scenario, I sought to utilize a specific Custom API provided by Microsoft. However, I encountered an obstacle as the Custom API was designated as private.
I aimed to incorporate the Custom API shown below into my Power Automate Flow. However, since it is labelled as private, the action becomes unusable within Flows.

What you can do instead is create your own Custom API and associate it with the relevant Plugin Type.
My Custom API
My Custom API Request Parameter
As demonstrated, I can now utilize the Action within my Power Automate Flow.
