Unable to set exercise name

Hello,

I'm attempting to use the proxy web api (via connect.garmin.com/.../workout) to send the following payload to create a new workout. I get a success back from the API and I am able to see the new workout in the Garmin-Connect UI, however regardless if I attempt to populate the "exerciseName" field, it doesn't appear.

Should I attempt to populate the exercise name in a patch/update call? Or is there some mysticism in how to get the API to take the value?

Thank you,
