Default EFB auto brightness issue for MSFS 2020 compatible aircraft in SU1 Beta


Hello!
In my aircraft (Daedalus BS214), which is an MSFS2020 aircraft, I managed to integrate the default EFB sim attachment into the VC for the MSFS2024-compatible version, offering users an extra great feature.
I am aware that the default EFB sim attachment is a native MSFS2024 sim object and is not normally compatible with MSFS2020 aircraft. However, in MSFS2024 v1.2.11.0, the integration was successful, and the basic functionality worked flawlessly.
In MSFS2024 Beta v1.3.19.0, the basic functionality still works, except for the EFB auto-brightness. The L:1:XMLVAR_EFB_AUTO_BRIGHTNESS_VALUE remains 1 during the night and does not adjust automatically based on time.
This issue occurs only in my MSFS2020 aircraft. Default and SDK aircraft samples (which are native MSFS2024) auto-adjust the EFB brightness correctly in Beta v1.3.19.0.

My question is: Is there any way to restore the EFB auto-brightness adjustment for MSFS2020-compatible aircraft?

If not, please let me know so I can remove the EFB VC integration from the aircraft. Without auto brightness adjustment, it becomes impossible to view the monitor or fly in a VR headset. However, that would be a pity since the basic functionality works fine and syncs with the avionics (G3X Touch V2 and PMS50 GTN750 VC integration).

Thanks in advance!
