How to use USB memory with QT

How to use USB memory with QT
Carrier: Toradex Dahlia V1.1D
CPU: i.MX8MMDL rev1.0
Cortex-A53: TorizonOS+Qt6
Cortex-M4: FreeRTOS

I’m developing a Qt application.
Are there any settings required to save data to USB within the application? Please tell me what to configure, including Docker settings.

Was self resolved
I changed /etc/fstab and confirmed that it is possible to write and read from the Qt application.
/dev/sda1 /media/usbfm auto noauto,user,rw,sync,gid=1000,uid=1000 0 0
