On the live map, when a user clicks on a diversion route, a pop-up appears with the name of the diversion route.
After speaking with support, I was informed that this information isn't surfaced in the data feed that we have access to.
There is an expectation that the data displayed on the map is available in the API response, even if we are required to perform a level of mapping.
It would be useful to surface this information so that we can meet parity with the live map.
