Khadas Edge 2 pro. I Can't move apps to external storage

OS Android12

Hello. I use My Khadas Edge 2 pro, for playing Android games with mouse and keyboard. I have an IO module for an external storage, micro SD card 256GB. The emmc is only 64GB it’s almost full and I can’t move the apps to the SD card.
How can I do this?

Expand the internal storage (emmc= 64GB) ?
Install the apps in the external storage = micro SD

Thanks for Your help!

I can’t install apps to the external storage.

@Etarot ,
At present, edge2 does not support installing apps on sdcard or transferring app data to sdcard.
