Rtl8812bu on Kali Linux

I have installed virtual box from Oracle. I am using Kali Linux from Offensive security, 2020b. I have Tp-Link archer t4u ( rtl8812BU) as wifi adapter. When I type "ifconfig" terminal does not show "wlan0" but when I type "ifconfig" it shows "wlan0". When using "airmon-ng" to enable monitor mode it fails. It shows error changing to mode using ip. The status of the wlan0 is down and I am unable to change it to up. Please help. I need to turn on monitor mode and package injection
