Attempting to Install KernelSU on Samsung Galaxy Tab Active5 (5G)

[TopHatProductions115new]

I recently got my hands on a Samsung Galaxy Tab Active 5 (5G). Here are some of the device details:

SoC: Exynos 1380
Android: 14
Kernel: 5.15.153-android13-3...

The KernelSU app shows Not installed at the very top. According to the online guide:

• https://kernelsu.org/guide/installation.html

, this means that my device is supported. After reading further, it seems that the GKI mode is suggested for this device (Samsung, with Knox).

There was one part of the guide that said If your device is a mobile phone, we recommend that you prioritize LKM mode, but I'm not sure if it applies for this tablet (though it can handle calls/SMS/MMS, and has GPS). Please correct me if I'm wrong.

When checking the available releases, I was unable to find a matching boot.img. How should I proceed?
