Need help install rtl8812au driver ( TP-Link Archer T3U pulse) on BBB

From last week, I’m struggling to install driver for TP-Link Archer T3U pluse USB wifi dongle on BB- Black.
Because TP-Link Archer T3U pulse use Realtek 8812au chipset, I found so many linux driver on Github. Sadly, I knew almost of all github maintainers support x86, or Raspberry-pi and so on, they DON’T support for Beaglebone-Black (AM335x).
So, so many time, I tried installed driver using Raspberry-pi setting or Making driver, and also I’v changed kernel version and upgrade from 5.x to 6.x and distro images.
During the installation or Making, I didn’t conflict any error massages.
However, I can’t find “wlan0” even though lsusb shows my TP-lInk USB as shown blow.

" & Bus 001 Device 002: ID 2357:0138 TP-Link 802.11ac NIC"

I really really need help the correct installation for driver and set-up wifi.

Board : Beaglebone-black element114 version
Image : bone-debian-10.3-iot-armhf-2020-04-06-4gb.img or am335x-debian-11.7-iot-armhf-2023-07-01-4gb.img
USB wifi : TP-Link Archer T3U pulse
Power : 2.5A using DC jack
Tried Driver : GitHub - morrownr/8812au-20210629: Linux Driver for USB WiFi Adapters that are based on the RTL8812AU Chipset - v5.13.6 or GitHub - aircrack-ng/rtl8812au: RTL8812AU/21AU and RTL8814AU driver with monitor mode and frame injection

I am not sure about the pulse, but the AC1300 Archer T3U Nano uses the 8812bu chipset. On a fresh Beaglebone Black with latest 11.7 image (Kernel 5.10…) I was able to get the cilynx 88x2bu driver to compile. I modified a script that is used to create the Falcon Pi Player image (FPP) which is often installed on the BBB. Here is my modified script:

cschill2020/explore-beagle/blob/master/wifi-drivers.sh

#!/bin/bash

# Fresh beagle may need to add linux headers:
# sudo apt-get install linux-headers-$(uname -r)

cd /opt
mkdir wifi
cd wifi
mkdir patches
cd patches

You can find the original script which installs many drivers:

Note you may have to install the linux-headers in order to compile the drivers. These were not in the IOT package OOTB:
sudo apt install linux-headers-$(uname -r)
