Using HappyModel ES900RX with Pixhawk

Hello, I want to use the HappyModel ES900RX - ELRS CRSF receiver
with Pixhawk 4. I have the latest FW, I connected the RX to the TELEM1 port, but in QgroundControl,
I do not see the parameter - RC_CRSF_PRT_CFG to set up the crossfire RC connection.

What am I doing wrong
