SO CLOSE TO GET HANDOFF TO WORK - HELP IS VERY MUCH APPRECIATED! PCE-AC56 & TP-LINK UB400

I made a post previously regarding Wi-Fi and bluetooth. I've finally gotten both to work! (see this post for reference: https://www.reddit.com/r/hackintosh/comments/1fndswj/comment/loi28sj/)

But now I have another issue. Airdrop works, but only one-way - I cannot receive anything as my bluetooth controllers state is NOT discoverable. How do I fix this?

I use a TP-Link UB400 & I've attached my kexts and bluetooth controller info.

My specs:

CPU: Intel i9900KS
HDD: NVME drive
Motherboard: ASUS ROG Maximus X Formula
GPU: AMD Radeon VII
RAM: 64 GB
OS: MacOS Sequoia
Wifi: ASUS PCE-AC56
BT: TP-Link UB400

Thanks in advance!
