Can't recognize bluetooth MIDI of my piano

Hi,

arecordmini can recognize bluetooth midi of my piano, and I can record/play with it.
However musescore 4 can only recognize Midi Through, but not midi of my piano.

version: MuseScore-Studio-4.4.1.242490810-x86_64.AppImage

$ arecordmidi -l
 Port    Client name                      Port name
 14:0    Midi Through                     Midi Through Port-0
129:0    CA501 MIDI                       CA501 MIDI Bluetooth

oui of the bluetooth midi is "E1:47:39:"

What can I do to make them know each other?

Thanks in advance.
