Excerpt from link above

" Tethering your iPhone to your Mac using Bluetooth is easy. However, while Bluetooth is a convenient and wireless way to get internet from your iPhone to your Mac, it is limited to 1 Mbps (Bluetooth 4) or 2 Mbps (Bluetooth 5). If you have fast LTE speeds on your phone, you might get better results with USB or Wi-Fi tethering. 

Note that Apple removed Bluetooth tethering in macOS Monterey and newer versions. "

Bluetooth PAN has been deprecated for years, and is no longer present in recent versions of macOS.
