Return participants for 1 person meetings (non dashboard API)

Is your feature request related to a problem? Please describe.

Describe the solution you’d like
The /metrics/meetings/{meetingId}/participants endpoint supports the pastOne query parameter (docs). Since we have a User level app, we can only use the /past_meetings/{meetingId}/participants endpoint. The docs for this endpoint state that the API doesn't return results if there's only one participant in a meeting. It would be great if this endpoint could also support pastOne, and return the single participant for 1 person meetings.

Describe alternatives you’ve considered
Currently we try to handle this on the client side, which can be difficult because we have to assume who the single participant was. Usually it’s the host of the meeting, but not always.
