Holybro telemetry radios don't show in Mission Planner

I recently switched to Holybro telemetry transceivers.I am using a APM, Plane. In Mission Planner Sik Radio section, neither of the
radio shows any data at all. The old transceivers showed up and responded to inputs. What do I need to do to to have them listed?
The telemetry radios function fine and show strong signal strength in the flight data screen.

if you find out please let me know, i have the same radio and the same problem i bay it holybro 9xx MHZ led solid but no communication
