Quadplane Autotune

How I can initiate the Q_Autotune for the Quadplane? In the flight mode, I can choose the Q_Hover but how can I initiate the Q_Autotune on the other switch. Pls let me know if anyone has does this before.

thank you in advance

You can add it as mode in 3 point switch. Switch to QLoiter or Qhover before switching to QAutotune.
Also make sure the aircraft is sufficiently tuned to recover.
