Bluetooth doesn't work

I might be totally missing something here, but it would seem I have Bluetooth on my new PC build. This is the mobo I have:

MSI MAG X870 TOMAHAWK WIFI AM5 ATX Gaming Motherboard, 4x SATA 6Gb/s, AMD Wi-Fi 7,USB 4.0

Windows 11 seems to detect it, yet when I try to phone link with my iphone, it's not picking up anything. Am I missing something here?
