Apple Broadcom Built-In Bluetooth in Device Manager not being detected

I'm using old intel based mac in which i installed windows 10

i'm having issues with the Bluetooth which is not being detected

the steps i have taken to solve this issue was:

• first, I searched for a suitable apple bluetooth driver for windows 10

this was the result

• second, i tried to detect bluetooth in my device manager but my device manager didn't show a bluetooth section

• third, when i try to open bluetooth in bluetooth settings, it went inside. but when i try to add my bluetooth headphone,

this comes up.

please suggest a solution for this.
